| Subject: | Invalid code in a2p appears when using exit function in BEGIN {} section |
The report below was originally filed in February 2012 in the Perl 5 bug queue at https://rt.perl.org/Ticket/Display.html?id=110606.
Since a2p is now maintained on CPAN, I am transferring the report to this queue.
Thank you very much.

This is a bug report for perl from glitchmr@myopera.com,
generated with the help of perlbug 1.39 running under perl 5.14.2.
-----------------------------------------------------------------
[Please describe your issue here]
If the script sent to a2p uses 'BEGIN {exit}', a2p will generate 'last
line', which causes awk to end with error without parsing every file line and
'END { }' section.
BEGIN {exit}
END { print "This should run!" }
Creates invalid Perl code which will make error instead of printing text:
#!perl
eval 'exec
C:\cygwin\home\gecko\tmp\perl-kpnbcrjndjmsxgdxbdoyvuagpsxapvmlmn\bin/perl -S
$0 ${1+"$@"}'
if $running_under_some_shell;
# this emulates #! processing on NIH machines.
# (remove #! line above if indigestible)
eval '$'.$1.'$2;' while $ARGV[0] =~ /^([A-Za-z_0-9]+=)(.*)/ && shift;
# process any FOO=bar switches
$, = ' '; # set output field separator
$\ = "\n"; # set output record separator
last line;
print 'This should run!';
[Please do not change anything below this line]
