On the FP side there is Yi[0]

The trick that Yi uses is quite clever and not very complicated:
keyboard input is passed to a lexer/parser which can be rewritten to
provide alternative bindings. Treating keyboard events like that
actually makes a lot of sense. It is not very specific to any
programming paradigm and could be implemented in C (with a recursive
descent parser if yacc is deemed to suck to much).
