Ok. In practice, I'll use Rakudo. It sounds like NQP just isn't worth the effort.

I don't know anything about bytecode or name mangling, but I do agree with the evils of F77. I personally refuse to learn F77, but I know that most scientific libraries haven't been ported to modern Fortran. Fortran 2003 introduced interoperability with C, so you can call Fortran functions from C and vice versa, but I think it'll be a long time before this is widely used in libraries. > NQP (and thus Rakudo) has its own mechanism for calling C libraries.

Thanks. I'll have a look. Cheers, Daniel. -- I'm not overweight, I'm undertall.
