Danny, you slay me! Only you would take a throwaway comment 
and turn it into a spell checking interpreter!

Combined with the parameter hints already in IDLE I think this

command line interpreter in general with some tidy up and 
maybe a toggle facility... Is Guido listening? (I think he 
still looks after IDLE?)
