in reply to ${Schwartzian transform} ?
At a first glance, I think your creating extra work rather than saving any. $_ is an alias, so when you include it in the anon. array, you are only passing a reference to the original value (ie. a scalar).
Your code is actually creating an extra reference to the scalar, (ie. copying the alias?), which it then has to dereference, hence doing slightly more work.
I *think*.
Examine what is said, not who speaks.

If I understand your problem, I can solve it! Of course, the same can be said for you.
