When an exception from autodie causes perl to exit(), the exit code 
should correspond to the value of $! as perl �natively� does as in the 
first example above.

Hi Felipe,

What version of autodie are you using?  Namely, I suspect that the
problem would be fixed in autodie 2.21 due to:

"""
        * INTERNAL : $" and $! are no longer arbitrarily messed with
          for no reason via autodie.  (They're still messed with when
          using Fatal.)
"""

Which would ensure that "$!" is (still) set to 2 and die should DTRT
from there.  Previously, $! would be "protected" by a local, causing it
to be reset to (in your example above) 0.

Hm. I was using 2.12. That sounds like it would fix the issue, but I 
tried updating my laptop�s autodie version to 2.22, to no avail:

felipe@Macintosh-19 14:25:15 /
 > perl -Mautodie -e'print $autodie::VERSION'
2.22
OK
felipe@Macintosh-19 14:26:53 /
 > cat | perl -Mautodie
`perl -Mautodie -e'open FH, "<", "yglzdfvxbfg"'`;
print ($? >> 8) . $/;
Can't open 'yglzdfvxbfg' for reading: 'No such file or directory' at -e 
line 1

Current Behavior:

$>perl -Ilib -Mautodie -e'open FH, "<", "qweqweqerwr"; print "Should not reach here\n"'; echo $?
Can't open 'qweqweqerwr' for reading: 'No such file or directory' at -e line 1
255

Felipe believes it should ext 2: "Normally Perl uses $! as the exit value when an exception ends the program."

#> perl -e'open FH, "<", "qweqweqerwr" or die'; echo $?
Died at -e line 1.
