It's totally common to to do some action despite that an exception has
been raised or not to cleanup stuff (like file descriptor is the obvious
example).

At the moment in OCaml you need to multiple layer or try/with to be able
to express this. it would be much nicer to allow this construction as a
proper idiom, not ad-hoc.

You probably don't write/read much python code then.

( I found 2 use of finally in felix's python code )

OCaml is a functional language, however it also contains imperative feature.

It doesn't seems so inappropriate to have a return statement, as long
it's not abused.
