This may be a good time to ask about how these variables which can be 
declared anywhere in the function scope are implemented.

void bar(bool foo) {
	if(foo) {
		int a = 1;
		...
	}
	else {
		int a = 2;
		...
	}

}

is the stack frame using two ints, or is the compiler seeing only one? I 
never bothered to check it out and just declared 'int a = void;' at the 
beginning of the routine to keep the stack frames as small as possible.
