in reply to Simulating Perl6 Meta/Hyper operators with pure Functional Programming

Nice. Re the syntax, you might be interested in Sub::Infix - it would enable syntax along the lines of:

my $iter = [@list1] |X| [@list2];

    Sub::Infix is indeed nice, really clever idea ... thanks! :)

    My problem with overloading so far was that I couldn't use wantarray, i.e. an overloaded '+' always has to return a scalar.

    But you don't have this problem, right?

    Anyway ATM I try to find solutions which work w/o overloading to avoid potential side effects.

    List::Gen for instance globally overloads the typeglob operator... 8-|

    > my $iter = [@list1] |X| [@list2];

    yep but the problem here is that the array are evaluated (i.e. listified) before being passed to the operator.

    I'd like to be able to inspect the code block before evaluating it.
