Separate parser program for 'intrusive'

[healytpk]

I've begun writing a short C++ program to take a normal header file like so:

	struct Monkey {
		int a;
		float b;
		char c[5];
	};

and turn it into:

	typedef char char_5[5];

	struct Monkey {
		BEGIN_VISITABLES(Monkey);
		VISITABLE(int, a);
		VISITABLE(float, b);
		VISITABLE(char_5, c);
		END_VISITABLES;
	};

I can show you what I have so far.

I think my question is, if you are going to run a code-gen tool over the code like this, why not generate the VISITABLE_STRUCT macro invocations instead? They are a bit simpler.
