Tip #641: Highlighting of method names in the definition (C++)

When editing big cpp files, it can be very convenient to highlight the method name
(the part after "::") in a method definition.

--> I use the following function in my .vimrc:

" Add highlighting for function definition in C++
function! EnhanceCppSyntax()
    syn match cppFuncDef "::\~\?\zs\h\w*\ze([^)]*\()\s*\(const\)\?\)\?$"
    hi def link cppFuncDef Special
endfunction

--> I have another line to call this function automatically when editing a C++ file:

autocmd Syntax cpp call EnhanceCppSyntax()

--> That's it! This doesn't work in all cases (for instance, it doesn't highlight constructors
using an initialization list on the same line) but it shouldn't highlight function calls
(such as "MyClass::MyStaticMethod( int foo );" )
Don't hesitate to extend the regular expression for a more accurate matching...
