syntactic sugar

syntactic sugar: [coined by Peter Landin] n. Features added to a
   language or other formalism to make it `sweeter' for humans,
   features which do not affect the expressiveness of the formalism
   (compare chrome).  Used esp. when there is an obvious and
   trivial translation of the `sugar' feature into other constructs
   already present in the notation.  C's `a[i]' notation is
   syntactic sugar for `*(a + i)'.  "Syntactic sugar causes
   cancer of the semicolon." --- Alan Perlis.

The variants `syntactic saccharin' and `syntactic syrup' are also recorded. These denote something even more gratuitous, in that syntactic sugar serves a purpose (making something more acceptable to humans), but syntactic saccharin or syrup serve no purpose at all. Compare candygrammar, syntactic salt.
