in reply to Lexical::Alias & subroutines

Someone else has pointed out this bug, too. I need to look at the source (the icky C source) to figure out what's wrong. It could be a bug... it probably has to do with the way I walk the pad in the module.

As far as changing the order of the parameters, I suppose I could make the module take an argument of "v=a" (variable to alias) or "a=v" (alias to variable).

As far as automagic my(), this is not a source filter, Jenda, it's merely an XS module that does some fancy footwork.

Maybe I'll look at Variable::Alias... have you? Update: ick (sorry BrentDax)... that's just a tie-based module. It won't help me solve my problem.

    Thanks for the info :-)

    I should invest some time in learning about source filters and later try to create a filter on top of your module that would allow me to write this as much as I'd like it as possible :-)

    P.S.: It'd be cool if you found a way to bypass the error in Perl, but I'm afraid I can't help you in this. My C skills are minimal.

      Lexical::Alias 0.04 will be coming to CPAN shortly. Two tiny changes -- a $SWAP global you can set to 1 if you want to send the arguments to the functions in the reversed order you specified, and a note about the 5.8.0 bug.

        I don't think the $SWAP global is the right implementation. It's too global :-)

        What about having

        alias $original => $alias;

        [download]
        and
        Alias $alias => $original;

        [download]
        or something like this. Or at least the SWAPing should be on package level. IHMO of course.

        Thanks, Jenda
