++ +When generating code it is important not to generate symbols that might clash with the code being wrapped. It is tempting to flout the standard or just use a symbol which starts with a single underscore followed by a lowercase letter in order to avoid name clashes. However even these legal symbols can also clash with symbols being wrapped. The following guidelines should be used when generating code in order to meet the standard and make it highly unlikely that symbol clashes will occur: ++ +17.4.3.1.2 Global names [lib.global.names] + +1 Certain sets of names and function signatures are always reserved to the implementation: + + * Each name that contains a double underscore (__) or begins with an underscore followed + by an upper case letter (2.11) is reserved to the implementation for any use. + * Each name that begins with an underscore is reserved to the implementation for use as + a name in the global namespace.165) + + 165) Such names are also reserved in namespace ::std (17.4.3.1).
