You mean imperatively?  Short answer: you can't and you shouldn't.

Slightly longer answer: you can possibly fudge something together using
the Identity monad from mtl, but that will involve wrapping/unwrapping
everywhere.

Learn to think about how to chain/group functions together to form more
of a "pipeline" rather than a sequence of statements.  Haskell =/= C.
