Almost.  To preserve the meaning, the composition syntax would need to
be

    (foo . bar . baz) x

or

    foo . bar . baz $ x

or something along those lines.  I favour the one with parens around
the dotty part, and tend to use $ only when a closing paren is
threatening to disappear over the horizon.

    do ...
       return $ case ... of
           ... -- many lines
