Certain coding rules in a programming language that make it easier for a person to write a program. For example, in Perl, the double dot operator is used to create multiple values. Writing ('A' .. 'Z') declares a range of values from "A" to "Z." In many other languages, each value has to be declared individually such as 'A','B','C' etc."Syntactic saccharin" is used synonymously with syntactic sugar; however, it also tends to refer to syntax that offers little or no value to the programmer, such as a symbol or word that is always required even though it adds no uniqueness to the expression. Contrast with syntactic salt.
(computing) Additions to a computer language that make code easier for humans to read or write, but that do not change the functionality or expressiveness of the language.
In fact, this is how lists are actually built, by consing all elements to the empty list, . The commas-and-brackets notation is just syntactic sugar, a more pleasant way to write code. So [1, 2, 3, 4, 5] is exactly equivalent to 1:2:3:4:5:. WB.
