Generalized version of bracket. Note, any monadic side effects
in m of the "release" computation will be discarded; it is
run only for its side effects in IO.
Generalized version of bracket_. Note, any monadic side effects
in m of both the "acquire" and "release" computations
will be discarded. To keep the monadic side effects of the "acquire"
computation, use bracket with constant functions instead.
