WOW really? Oh man, thank you for telling me!

Well, unfortunately I've never done this.

(playing tricks again you funny little bastard? Ha ha ha ... yawn)

The approach of hashes with

{ name1 => sub { }, name2 => sub { }, }

is well known. but it's sufficiently different to easily introduce errors.

Especially when copying existing code, things like comma-separation, indentation, positions of names, ... (see also Eily's comment).

Secondly and more importantly the need to benchmark often comes if code has already been written and experimenting starts with cloned forms of

sub do_something { # not fast enough }

then called

sub do_something_old { ... }

or

sub do_something_1 { ... }

And I don't think I'm alone, two other monks already asked about filtering some subs out of a package and/or ignoring imported subs.

Now if you don't like a convenience module to facilitate this kind of benchmarking, better don't use it.

    As clearly identified in the post to which I linked, (so no "trick"). Instead you write crap like this.


    With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
    "Science is about questioning the status quo. Questioning authority".
    In the absence of evidence, opinion is indistinguishable from prejudice.

      Again resorting to vulgarities when your tricks fail?
