Re^6: A wholly inadequate reply to an Anonymous Monk

S01 says "we sure wish so".

As for it actually happening..

Perl 6 has drastically different calling conventions than Perl 5, and even now has characters in its standard library functions that are prohibited in Perl 5 ("-"). The only way I see them inter-operating is through some hairy foreign function interface. Let's take this example from S01:

    use v6;
    # ...some Perl 6 code...
    {
        use v5;
        # ...some Perl 5 code...
        {
            use v6;
            # ...more Perl 6 code...
        }
    }

How would this work with some real code dropped in:

    use v6;
    
    multi sub foo-bar(Str $a, Str $b) { "str/str" }
    multi sub foo-bar(Str $a, Int $b) { "str/int" }
    multi sub foo-bar(Str $a, Num $b) { "str/num" }
    multi sub foo-bar(Str $a, Array $b) { "str/num" }
    {
        use v5;
        # oh shit, what now? do I:
        foo-bar("1", "2"); # syntax error
        call_perl6_func("foo-bar", "1", "2"); # calls, but breaks sinc
+e Perl5 has no types
        # Maybe this instead:
        call_perl6_func("foo-bar", Perl6cast("Str", "1"), Perl6cast("S
+tr", "2");
        {
            use v6;
            # now how do I call perl 5?
        }
    }

That's just the simple case of calling a subroutine. How about the totally incompatible object systems?

Does someone have a plan for getting this working?
