I'm not sure if the objection is to having 'Array.rev*' altogether or
having two different versions of this function.  Well, the point of
having 'Array.rev' is simply because there is a 'List.rev'.  'Array.-
rev_in_place' is an extension to the standard set of common functions
which only applies to the special case of arrays because arrays are
mutable.

OK, but conversely List.find_all is defined as identical to
List.filter.  Hashtbl.find_all is quite a different function.  It
returns all values associated with a single key, and only makes sense
because of a peculiarity of Hashtbl, namely that one can associate
multiple values with a key.
