    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,
