What about extending haskell (or ghc) with mixfix operators, Agda style?. At
first sigth it would permit the creation of custom control structures and

3. define suitable abstractions for your special case
4.

The when and unless functions might come in handy too (both have type
forall (m :: * -> *). (Monad m) => Bool -> m () -> m ())

I recall reading some tutorial about how you can use the Maybe monad
