If you're going to write that into some documentation, I wish you'd
make default say that it's exception suicide.
given( my $_ = $@ ) {
...
default { say '$@ committed suicide' }
}
Semi-recently at work I found that a few buggy exception objects in
the global $@ were clearing themselves out of $@ as a side effect of
examining them for truth. It's quite annoying and mysterious when it
happens.
