I've noticed that I can't chomp as I read from tied filehandles. perltie says tied filehandles are "partially implemented" so I'm not sure if this is a bug with perl or my code. I noticed the problem using IO::Socket::SSL, here's a smaller test case:
package Foo; sub TIEHANDLE { $obj = {}; bless $obj, $_[0]; } sub READLINE { return "foobar\n"; } package Main; use Foo; tie(*test, Foo); chomp($data = <test>); print join(", ", map { ord($_) } split(//, $data)) . "\n"; chomp($data); print join(", ", map { ord($_) } split(//, $data)) . "\n";
