My basic rule is "if you are calling something p5ish from p6, if it expects an arrayref you give it an array (which will be passed as a p5 arrayref) and if it expects a list you probably need to slip it with |". Perl 5 code is still Perl 5 code, and the Perl 5 sub calling convention flattens everything into a single list unless you've told it otherwise with a prototype (and even then it will force an arrayref, because the actual calling convention still uses a flat list); this cannot be changed without altering the guts of Perl 5 in ways that are quite beyond Inline::Perl5 or any other possible plugin. Perl 6 can be thought of as considering an array or hash or etc. as a reference unless told otherwise (which is why there is prefix:<|> or .slip, for those cases when you need to tell it otherwise). (I haven't checked, Inline::Perl5 may actually slip for you if it knows it needs to; XS provides an API to determine the prototype of a function.) -- brandon s allbery kf8nh sine nomine associates allber...@gmail.com ballb...@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
