You forgot that it is very poor style to alter the input data in a map. You wrote map { chomp; $_ => undef} but you should have written map { local $_ = $_; chomp; $_ => undef }.

Or... there is some case where the `local $_ = $_` triggers some bug so in that case you'd have to say map { my $key = $_; $key => undef } to be really safe.
