Wow, that was an unexpected answer... :-)

With post "I should've known better!" in mind, I was trying to understand if $_ is modified only in the scope of the substitution from the OP's attempt:

foreach (keys %{$ref_cookie}) {
  push(@{$self->{cookies}}, {$_=~s/^-//}, $ref_cookie->{$_}});
}

I didn't pay much attention on the context or what keys should be. I see your point and agree.

Now, if OP has both types of keys, with and without leading hashes:

-foo => 'food',
bar  => 'barl'

[download]

the code should be:

  push @{$self->{cookies}}, /^-?(.*)/, $ref_cookie->{$_};

[download]

to get all four values in the array.

BTW, I'll have to practice more with push of undef in arrays...
