Has anyone used the FFI interface or similar to link libcurses or similar?  I 
could try to talk ANSI terminal sequences directly, but querying terminal state 
with these seems pretty painful.  (At the very least one has to put standard 
input into a non-blocking state, and I found the Basis documentation on how I 
might do this very confusing.)  And then one is breaking the very abstraction 
that curses is trying to provide...

As a bare minimum for example, I'd like to get the width of the current 
terminal.
