Or even better-better as:

chomp(my @info = grep /\S/, <READ>);

Shouldn't that be:

my @info;
chomp(@info = grep /\S/, <READ>);

so that @info is accessible later?

No. It works as-is. There's no new scope there. I use that idiom all the time:

chomp(my $input = <FOO>);

-- Randal L. Schwartz, Perl hacker

@info will still be visible after the chomp(). There is no enclosing scope there to cause the lexical nature to release the array.
