Reloading an entire Module can be icky if in addition to undefining the
%INC entry you need to undefine the entire symbol table (e.g. to get rid
of garbage accumulated in that namespace), in which case objects of that
package get re-blessed into the __ANON__ package.

If you just have to modify methods of a class or functions of a module
or package, you could go with AutoReloader by yours truly, which is a
drop-in replacement for AutoLoader and designed for just your type of
apps in mind (see http://search.cpan.org/search?query=AutoReloader
and http://perlmonks.org/?node_id=600805 ).

Of course that means splitting up your module into separate files as
e.g. POSIX in the core distribution.
