^ There's the problem.  Surely something could be worked out for
Windows, too.  However, expecting individual programmers to
reinvent those wheels is a violation of the DRY principle.

I think it would be handy to have key_pressed, or preferably
"getch", as a part of the standard library.  

I could be wrong, though.
