As more and more D2 functions become pure in my code and in Phobos, something
like a -disablepure compiler switch (and printf/writeln inside debug{}) may
allow more handy debugging with prints (if the purity is well managed by the
compiler then I think disabling the pure attributes doesn't change the program
output).
