The article doesn't mention Perl at all but it did have some direct influences on Ruby.

Even Ruby's trailing blocks syntax are an homage to Perl's block list subroutines:

  # first Ruby example in article
  users.select { |u| u.admin? }.map(&:email)

  # using Perl's block list
  map {$_->email} grep {$_->is_admin} @users;
