Oops I missed a require:

=> true

It does work, and, though it doesn't get arrow keys, it's good enough 
for my intents and purposes.

NB if you *do* want arrow keys you'll want to wrap _getch or _getkbhit, 
like rb-readline does.  See also [1]..

-r

For google's sake, here's what it does when you *don't* first require 
io/console:

>> STDIN.getch
NoMethodError: undefined method `getch' for #<IO:<STDIN>>
