Microsoft's .NET Common Language Infrastructure (CLI) specification allows code written in 40+ different programming languages to be combined into a final product. Because of this, identifier/reserved word collisions can occur when code implemented in one language tries to execute code written in another language.
Thus using reserved words, the tokens for __foo and foo are (identifier, __foo) and (identifier, foo) – different values in the same category – while in stropping the tokens for __foo and foo are (keyword, foo) and (identifier, foo) – same values in different categories. These solve the same problem of namespace clashes in a way that is ...

longer identifiers may be disfavored because of visual clutter; It is an open research issue whether some programmers prefer shorter identifiers because they are easier to type, or think up, than longer identifiers, or because in many situations a longer identifier simply clutters the visible code and provides no perceived additional benefit.
Code can be modularized into functions defined with keyword function. PHP supports an optional object oriented coding style, with classes denoted by the class keyword. Functions defined inside classes are sometimes called methods. Control structures include: if, while, do/while, for, foreach, and switch. Statements are terminated by a semicolon ...

For example, in C#, the "@" prefix can be used either for stropping (to allow reserved words to be used as identifiers), or as a prefix to a literal (to indicate a raw string); in this case neither use is a sigil, as it affects the syntax of identifiers or the semantics of literals, not the semantics of identifiers.
32-bit compilers emit, respectively: _f _g@4 @h@4 In the stdcall and fastcall mangling schemes, the function is encoded as _name@X and @name@X respectively, where X is the number of bytes, in decimal, of the argument(s) in the parameter list (including those passed in registers, for fastcall).
