I'm +/-0 on ifM, but that doesn't seem to be in the original proposal anyway. I can see the value in it, but I've never really needed it. I would probably use f >>= bool x y in practice.
agreed. additionally, while when/unless/whenM/unlessM gets rid of a `return ()` branch, ifM does not. In situations where I have branching code containing more than just properly curried functions I will prefer an intermediate variable if I get to use the language built-in if/then/else that gets syntax highlighted and avoids parentheses. `$ do` avoids parentheses with when/unless/whenM/unlessM, but with a second branch the parentheses return for both.
