One minor nit, and perhaps I'm just misunderstanding some subtle use of the terminology, but you say: "In Perl 5, you get a copy of the arguments to work with in @_." However, this isn't true (again, unless I'm misunderstanding you). @_ is a by-reference list of positional parameters (Perl 5 only has positionals) which are all read-write, which it's interesting to note, is impossible in Perl 6... well, at least in Rakudo, as I'm not sure what the behavior is supposed to be, but a slurpy positional list in Rakudo that's declared "is rw" does not change the values passed in: sub foo(*...@_ is rw) { @_[0] = 1 } my $a = 0; foo($a); say $a; # 0 Kind of interesting that you can't easily emulate Perl 5's parameter passing... -- Aaron Sherman Email or GTalk: a...@ajs.com http://www.ajs.com/~ajs
