/*
The implementaiton of the upfront constructors involves doing three things:
* Validate the arguments given to construct the intended type of AST is valid.
* Construct said AST type.
* Lock the AST (set to readonly) and return the valid object.
If any of the validation fails, it triggers a call to log_failure with as much info the give the user so that they can hopefully
identify the issue without having to debug too much (at least they can debug though...)
The largest of the functions is related to operator overload definitions.
The library validates a good protion of their form and thus the argument processing for is quite a bit.

To check if a definition is for a constructor we can go straight to the opening parenthesis for its parameters
From There we work backwards to see if we come across two identifiers with the same name between an member access
:: operator, there can be template parameters on the left of the :: so we ignore those.
Whats important is that its back to back.
This has multiple possible faults. What we parse using this method may not filter out if something has a "return type"
This is bad since technically you could have a namespace nested into another namespace with the same name.
If this awful pattern is done the only way to distiguish with this coarse parse is to know there is no return type defined.
TODO(Ed): We could fix this by attempting to parse a type, but we would have to have a way to have it soft fail and rollback.

/*
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.
