I'm currently hacking more scanners:

- Scanning/warning, if function return value is discarded, i.e.

	int f() { ... }

	f(); // Warn

	cast(void)f();	// Don't warn

- Warning for suspicious looking infinite loops, i.e.

	for(;3.1415926535894;) { ... }	// Warn

	for(;;) { }	// Don't warn


There are some problems to make them correct, since DParser does not 
always store all necessary information, e.g. "for(;true;)" = "for(;;)"

I probably include scanning of constant if/switch values with the loop 
scanning... That general purpose walking class makes implementation of 
these kinds of checkings relatively easy.

There will surely missing / wrongly working pieces in the code, but those 
can be corrected later :)
