in thread How can I retrieve the link with the highest number in it using Perl?

Why do I have to call the find_all_links function with no arguments to it so my @links array gets filled?
Perhaps you were distracted by the multi-line statement?

This:

my @links = map {$_->text} grep {$_->text =~ m/^\d+$/} $mech->find_all_links();

is equivalent to this:

my @links = map {$_->text} grep {$_->text =~ m/^\d+$/} $mech->find_all +_links();

(When I first read the original, I didn't see the lack of semicolon on line 1, which made me think it was an example from Damian's time reversed variables.)

Then read right to left.
