# Pre-5.10 perls pollute %INC on unsuccesfull module
# require, making it appear as if the module is already
# loaded on subsequent require()s
# Can't seem to find the exact RT/perldelta entry
#
# The reason we can't just use a sane, clean loader, is because
# if a Module require()s another module the %INC will still
# get filled with crap and we are back to square one. A global
# fix is really the only way for this test, as we try to load
# each available module separately, and have no control (nor
# knowledge) over their common dependencies.

# we want to do this here, in the very beginning, before even
# warnings/strict are loaded
