"you can't pass things to functions"
How did you come up with that wild misconception? You can pass arguments to functions just fine in RPerl.

And yes, I'm friends with Raiph. He's a super nice guy. What's your point, a weak attempt at ad-hominem personal attack, maybe? Come on. We all know Perl 6 has issues, so does Perl 5, deal with it.

Perling,

    If you forbid @_ you forbid function arguments. Do you even lift, bro?
      YOU'RE RIGHT! You hereby officially win 1 brownie point for helping me figure out that the allowable exceptions for using $_ and @_ are not clearly-enough spelled out in The Low-Magic Perl Commandments. Thanks to you, 4 commandments have been updated:

      LMPC #42. Thou Shalt Use Real Prototypes (“our int__array_ref $f = sub {(my string $x, my int $y) = @_; ...}”, @_ Allowed)

      LMPC #43. Thou Shalt Not Use Perl Prototypes (AKA Parameter Context Templates)

      LMPC #52. Thou Shalt Use Lexical-Scope Grep & Map (“map { my int $var = $_; foo($var); } @{$vars};”, $_ Allowed)

      LMPC #53. Thou Shalt Not Use Dynamic-Scope Grep Or Map (“map { foo($_); } @{$vars};”, $_ Disallowed)

      I appreciate your help in tracking down that bug! :-)

      Perling,
