SYNOPSIS
        object to_object(string arg)
        object to_object(closure arg)
        object to_object(object arg)

        (object)<value>

DESCRIPTION
        The argument is converted into an object, if possible.

        For strings, the object with a matching object_name() is
        returned, or 0 if there is none, as find_object() does.

        For (bound!) closures, the object holding the closure is
        returned (for 'alien lfun closures' this is the object which
        created the closure, not the object the lfun is defined in).

        Objects and the number 0 return themselves.
