Making the cast implicit is the whole point. Of course its trivial to 
add a method like ConstCast() and it's better than implicit 
conversion if you ignore backward compatibility. But if you don't 
ignore it, then you have to consider lots of code that _will break_ 
unless the cast is implicit. And it's not only wxMSW implementation, 
but any (user) code that uses the Win32 API directly.

Vaclav
