Nik Clayton gave an excellent talk to Milton Keynes Perl Mongers last
year about testing legacy code that included  using overloading to
change the behaviour of things like open().  You could use a similar
approach to simulate, if not manufacture, edge cases.

The slides are online:

Effectively, I imagine this has the same effect as using Hook::LexWrap
as Adrian Howard suggested.  As always, TIMTOWTDI.
