If you're going to use isa()/can() and you think your code might be
used by someone who writes tests, you should be using them as methods
anytime you have an object. People using Test::MockObject rely on the
method form of isa() being overrideable.

I haven't used T::MO myself but I think I'm accurately relaying what
the Test::MockObject users are typically complaining about.
