Parsing D Maybe Not Such a Good Idea <_<;

[cy via Digitalmars-d]

So I was toying with the idea of writing a D parser, and this 
happened.

const(/*
                                D is kind of hard to parse. /*
                        /**/
                        int//) foo(T//
                        ) foo(T//
                                                )(T /* I mean,
                                                                                
 seriously
                                                                                
 */ bar)
        if ( is (T == // how on earth do they do it?
                 int) ) {
                return
                        cast /+  where does the function name /+ even start? +/
                                                +/
                        ( const (int) )
                        bar//;}
                        ;}
                        
void main() {
        import std.stdio;
        writeln(foo(42));
}
I don't think I'm going to write a D parser.
