No, you are correct, but these are currently not in t/lib (unless
someone snuck them in....)
Of the modules you listed above, only one (IO::String) is required by
the core modules. The others are not. Users shouldn't be forced to
install Algorithm::Diff or IO::ScalarArray just to run tests, so
anything not required should go into t/lib if at all possible.
If there any reasons (OS issues, list of prereqs) which preclude
adding these to t/lib we need to ask ourselves (1) why we are using
that module in the first place? And, if there is a good reason, (2)
can we skip them if they aren't present? Both of those options are
