Has to be something really stupid, but the following never finish
(running Python 2.5.1 (r251:54863, Jan 10 2008, 18:00:49)
[GCC 4.2.1 (SUSE Linux)] on linux2).
The intention is to match C++ identifiers, with or without namespace
qualification, with or without arguments (e.g. variables, functions and
macros).
The following should be accepted:
main
main(int,char**)
::main
std::cout
::std::cout
NDEBUG
Thanks for any help.
And yes, I'm a total beginner when it comes to Python, but it seems
very strange to me that a regex match on a finite length string
doesn't terminate
