=== Syntactic salt ===
The metaphor has been extended by coining the term ''syntactic salt'', which indicates a feature designed to make it harder to write bad code.<ref>{{cite web |url=http://www.catb.org/jargon/html/S/syntactic-salt.html |title=The Jargon File - syntactic salt |date=2003-06-12 |access-date=2018-03-19 |archive-url=https://web.archive.org/web/20030612232319/http://www.catb.org/jargon/html/S/syntactic-salt.html |archive-date=2003-06-12}}</ref> Specifically, syntactic salt is a hoop that programmers must jump through just to prove that they know what is going on, rather than to express a program action.

In [[C Sharp (programming language)|C#]], when hiding an inherited class member, a compiler warning is issued unless the <code>new</code> keyword is used to specify that the hiding is intentional.<ref>{{cite web|url=http://msdn.microsoft.com/en-us/library/435f1dw2.aspx|title=new Modifier (C# Reference)|publisher=Microsoft|work=microsoft.com|access-date=3 August 2015}}</ref> To avoid potential bugs owing to the similarity of the [[switch statement]] syntax with that of C or C++, C# requires a <code>break</code> for each non-empty <code>case</code> label of a <code>switch</code> (unless <code>[[goto]]</code>, <code>return</code>, or <code>throw</code> is used) even though it does not allow implicit ''fall-through''.<ref>{{cite web |url=http://msdn.microsoft.com/en-us/library/vstudio/06tc147t.aspx |title=switch (C# Reference) |publisher=Microsoft |work=microsoft.com |access-date=3 August 2015}}</ref> (Using <code>goto</code> and specifying the subsequent label produces a C/C++-like ''fall-through''.)

Syntactic salt may defeat its purpose by making the code unreadable and thus worsen its quality&nbsp;– in extreme cases, the essential part of the code may be shorter than the overhead introduced to satisfy language requirements.

An alternative to syntactic salt is generating compiler warnings when there is high probability that the code is a result of a mistake&nbsp;– a practice common in modern C/C++ compilers.

=== Syntactic saccharin ===
Other extensions are ''syntactic [[saccharin]]'' and ''syntactic [[syrup]]'', meaning gratuitous syntax that does not make programming any easier.<ref>{{cite web|url=http://www.catb.org/jargon/html/S/syntactic-sugar.html|title=syntactic sugar|work=catb.org|access-date=3 August 2015}}</ref><ref>{{cite book|url=https://books.google.com/books?id=OfWiZNhyRGgC&q=syntactic+saccharin+example&pg=PA93|title=Mathematics of Program Construction|access-date=3 August 2015|isbn=9783540438571|last1=Boiten|first1=Eerke A.|last2=Möller|first2=Bernhard|date=2002-06-26|publisher=Springer }}</ref><ref>{{cite book |last=Dean |first=Thomas |date=2004 |title=Talking with Computers: Explorations in the Science and Technology of Computing |url=https://archive.org/details/talkingwithcompu00dean |url-access=registration |publisher=Cambridge University Press |page=[https://archive.org/details/talkingwithcompu00dean/page/115 115] |isbn=9780521542043}}</ref><ref>{{cite conference |url=https://pdfs.semanticscholar.org/f396/bc99c7e444f70db69fb3f42e76e94e9d39a3.pdf |archive-url=https://web.archive.org/web/20170331115339/https://pdfs.semanticscholar.org/f396/bc99c7e444f70db69fb3f42e76e94e9d39a3.pdf |url-status=dead |archive-date=March 31, 2017 |chapter=Fine control of demand in Haskell |last1=Harrison |first1=William |last2=Sheard |first2=Tim |title=Mathematics of Program Construction |series=Lecture Notes in Computer Science |date=July 8–10, 2002 |volume=2386 |publisher=Springer Berlin Heidelberg |book-title=Mathematics of Program Construction: 6th International Conference, MPC 2002, Dagstuhl Castle, Germany, July 8–10, 2002.

=== Sugared types ===
Data types with core syntactic support are said to be "sugared types".<ref>{{cite thesis |type=PhD |last=Chugh |first=Ravi |date=2013 |title=Nested Refinement Types for JavaScript |publisher=UC San Diego}}</ref><ref>{{cite web|url=http://clang.llvm.org/doxygen/SemaCodeComplete_8cpp_source.html|title=C Language LLVM Documentation|work=clang.llvm.org|access-date=30 June 2020}}</ref><ref>{{cite web|url=https://medium.com/@slavapestov/the-secret-life-of-types-in-swift-ff83c3c000a5|title=The Secret Life of Types in Swift|work=medium.com/@slavapestov| date=14 July 2016 |access-date=30 June 2020}}</ref> Common examples include quote-delimited strings, curly braces for object and record types, and square brackets for arrays.
