Not really "syntax error", but runtime error. The function is expecting
an array, and it gets a string.
This is perfectly legal:
sub foo(@arr) {...}
my $var = [1,2,3];
foo($var);
And it works just as if there were an @ on the front of var.

Pugs 6.0.0 released.
(Sorry for the cross-posting; announcement of future releases will appear only on the perl6-compiler list.) Quite appropriately, on Day 6 of Pugs, I have released Pugs 6.0.0. It should be on a CPAN near you in a few hours, under the Perl6::Pugs namespace. You may install it from the CPAN shell just like any other CPAN module, provided that you have GHC on your system. This initial release offers the following features: * Evaluation of most simple Perl6 expressions. * Junctions and chained comparisons. * Interactive shell and #!/usr/bin/pugs support. See the Perl6::Pugs POD for more details. I will keep an implementor's journal in use.perl: http://use.perl.org/~autrijus/journal/ Project-related information are currently kept on the Haskell Wiki: http://autrijus.org/pugs/ Special thanks to many people on irc.perl.org #perl, especially Juerd, for last-minute testing. Also I'd like to thank freenode #haskell for tolerating my newbie questions, as well as various helpful clarifications from perl6-language. Cheers! :-) Feedbacks, patches, ideas and other suggestions are very much welcome. Thanks, /Autrijus/ pgpxL2wAQuqMw.pgp Description: PGP signature
