/*
	This is a mess, but it works
	Parsing typename is arguably one of the worst aspects of C/C++.
	This is an effort to parse it without a full blown or half-blown compliant parser.

	Recursive function typenames are not supported, if they are used expect it to serailize just fine, but validation with AST::is_equal
	will not be possible if two ASTs share the same definiton but the formatting is slightly different:
	AST_1->Name: (* A    ( int   (*)    (short a,unsigned b,long c) ) )
	AST_2->Name: (* A       ( int(*)(short a, unsigned b, long c) ) )

	The excess whitespace cannot be stripped however, because there is no semantic awareness within the first capture group.
