Many more improvements from Niels Thykier, great hero of the
free people. Plus a compatibility patch from Zefram, keeper
of Carp.
SPEED / INTERNAL : Through the magic of globally reuseable
core leak trampolines, autodie is even faster when used across
multiple pacakages.SPEED / INTERNAL : Caches used for keeping track of
fatalised subroutines are faster and leaner.SPEED / INTERNAL : Core subroutine wrappers are now lazily
compiled.SPEED / INTERNAL : Using autodie while autodie is already in
effect is now faster and more efficient.INTERNAL : $" and $! are no longer arbitrarily messed with
for no reason via autodie. (They're still messed with when
using Fatal.)SPEED / INTERNAL : The ':all' tag hierachy is expanded
immediately, in an efficient fashion.INTERNAL : Numerous minor clean-ups. Dead variables removed.
Typos fixed.SPEED / INTERNAL : import() and _make_fatal() cache more
aggressively, reducing CPU overhead.TEST: Compatibility with Carp 1.32 (thanks to Zefram).
