In computer science, syntactic sugar is syntax within a programming language that is designed to make things easier to read or to express. It makes the language "sweeter" for human use: things can be expressed more clearly, more concisely, or in an alternative style that some may prefer.
List comprehension is a syntactic construct available in some programming languages for creating a list based on existing lists. It follows the form of the mathematical set-builder notation (set comprehension) as distinct from the use of map and filter functions.
A similar example was the lock screen command that stopped visual updating, which was a short form for set the lockscreen to true, where lockscreen is a property of HyperCard itself—also a container. Many examples of this sort of syntactic sugar were found in HyperTalk, in order to simplify the syntax and improve readability of common code.
In this example, it's used for instantiating the OUT class, which is the class for the standard output. The + operator has been overloaded by the class to append the string passed as argument to the stream. Operators such as + are syntactic sugar for conventionally named method calls: a + b stands for a.plus(b). The usual arithmetic precedence ...
the Add method, which adds a key and value and throws an exception if the key already exists in the dictionary; assigning to the indexer, which overwrites any existing value, if present; and; assigning to the backing property of the indexer, for which the indexer is syntactic sugar (not applicable to C#, see F# or VB.NET examples).
In the programming language Dylan, which is an object-oriented language that supports multimethods and doesn't have a concept of this, sending a message to an object is still kept in the syntax. The two forms below work in the same way; the differences are just syntactic sugar. object.method(param1, param2) and method (object, param1, param2)

A programming language specification can take several forms, including the following: An explicit definition of the syntax and semantics of the language. While syntax is commonly specified using a formal grammar, semantic definitions may be written in natural language (e.g., the approach taken for the C language), or a formal semantics (e.g., the Standard ML [3] and Scheme [4] specifications).
