I think that this will run your Perl code with STDIN fed and STDOUT/STDERR catched properly:

use IPC::Run 'run'; my ($stdout, $stderr); run [ qw/perl -e/, $code ], '<', \$args, '>>', \$stdout, '2>>', \$stde +rr;

Example run:

$ perl my $code = q[use feature 'say'; say for 1..10; warn 'zzz'; $z = <STDIN +>; $z=~y/a-z/A-Z/; say $z]; my $args = q[this is STDIN, why not?]; use IPC::Run 'run'; my ($stdout, $stderr); run [ qw/perl -e/, $code ], '<', \$args, '>>', \$stdout, '2>>', \$stde +rr; print "STDOUT: $stdout\n"; print "STDERR: $stderr\n"; __END__ STDOUT: 1 2 3 4 5 6 7 8 9 10 THIS IS STDIN, WHY NOT? STDERR: zzz at -e line 1.

__DATA__ will be broken unless you use real files instead of -e 'code' above. Feeding the code to STDIN (with "\n__END__\n" between the code and actual STDIN) may also work, but can break in strange ways with syntax errors in code.

Sorry if my advice was wrong.
