Hey, this is exactly what I wanted! I'll have to remember to search CPAN more thoroughly next time. Thanks!

    If you dont want to introduce a dependency on IO::Capture::Stderr, and you only want to capture the STDERR from the die() calls, you could try this

    my @dieings; sub my_die() { # localise capture to just my_die() calls... local $SIG{__DIE__} = sub { push(@dieings, @_); }; die(@_); } #... time passes my_die("now we need to capture"); #... time passes print "now we need to report " . Dumper(\@dieings);

    It may be possible to replace die() with this at compile time, I've never tried the *CORE::GLOBAL trick with die(), only open(). I know there are some perl functions where not even compile-time replacement works, die() might be one of those.
