but that doesn't work either; the problem is that $@ gets unlocalized after
eval assigns to it, even when the argument to die has nothing to do with $@.
perl -le 'eval { local $@; die "yabbazabba" }; print $@||"nothing there"'
So including an attempt at pass-by-copy in the documentation of what
doesn't work (1) indicates that thinking it might be a pass-by-copy problem
is reasonable and (2) documents by example quoting as a method to force
pass-by-copy.
