Subject: Problem in using inline C with perl6
Hi All,

I am trying to use the C extention feature with perl6. Although it worked 
fine with perl5, the C extention is different from perl5 to perl6. I tried 
to use the same as following :


h2xs -PAXn Math::Simple

ashiva@ubuntu:~/Parrot/rakudo/Inline-0.44/Math-Simple$ cat math.pl
#!/usr/bin/perl6

use lib './lib/Math/.';
use Math::Simple;

print add(2, 3);
print subtract(3, 2);
ashiva@ubuntu:~/Parrot/rakudo/Inline-0.44/Math-Simple$

ashiva@ubuntu:~/Parrot/rakudo/Inline-0.44/Math-Simple$ cat 
lib/Math/Simple.pm
package Math::Simple;
$VERSION = '1.23';

use base 'Exporter';
@EXPORT_OK = qw(add subtract);
use strict;

use Inline C => 'DATA',
           VERSION => '1.23',
           NAME => 'Math::Simple';

1;

__DATA__

=pod

=cut

__C__
int add(int x, int y) {
  return x + y;
}

int subtract(int x, int y) {
  return x - y;
}


But I keep getting this error :

ashiva@ubuntu:~/Parrot/rakudo/Inline-0.44/Math-Simple$ perl6 math.pl
===SORRY!===
arglist case of use not yet implemented. Sorry.
at math.pl:3
ashiva@ubuntu:~/Parrot/rakudo/Inline-0.44/Math-Simple$

I know virtually nothing about perl6, but it would seem that the error is in 
relation to:

use lib './lib/Math/.';

(Providing args such as './lib/Math/.' to a "use" directive is apparently 
not yet supported.)

So the error really has nothing to do with Inline itself.

I was told a few years ago that perl6 doesn't have XS. That being so, I 
don't see how Inline::C (in its current form) could ever work with perl6 - 
because, under the hood, Inline::C does little more than write (and compile) 
an XS file.

Cheers,
Rob
