Exactly the same thought here. Also:

int i = ...;
char[] x = "You pressed button " + i;

Oops... doesn't compile. To fix it:

import std.string;

int i = ...;
char[] x = "You pressed button " + toString(i);

But wait, if that piece of code is inside a method of a class, than 
(WHY?) it thinks it's the toString() method, so you end up writing:

import std.string;

int i = ...;
char[] x = "You pressed button " + std.string.toString(i);

Those are the cases I find D not nice.
