  • You know, I never thought of applying attributes to forward declarations. You've gotten me thinking. That's probably a bad thing ... :)

  • Oh dear, what an amazingly cool trick.

    You've got me thinking as well.

    But first I'd like to find out if that trick is a) Expected b) Going to keep working c) Back-compatible for some reasonable length (5.6.1 being probably the best target to even consider it).

  • use P5NCI::Attribute library => 'nci_test', path => 'src';

    sub double_int :NCI( double_int => ii );


    versus


    use P5NCI::Easy # *cringe*
            library => 'nci_test',
            path => 'src',
            connect => [ 'double_int:ii' ];


    or perhaps


    use P5NCI::Simple nci_test => 'src', {
            double_int => 'ii',
            };


    Or maybe some combination or variant.

    Have a look at the import syntax for [cpan.org]
    • If only want to install a thunk as the name of the bound function, those all work too. This example doesn't really show that using different names here is trivial.

      I do think this works on Perl 5.6.1. At least, the only thing I worry about is the attribute trick. (See the first code example on page 232 of Camel 3 for why I don't worry much.)
