Parrot's NCI (Native Call Interface) lets you load a dynamically linked library/shared object and call functions in it (I once wrote a script that auto-gen'd Parrot calls for the entire Win32 API). Then you can write a Perl6 module that inlines PIR (Parrot code) that loads your Parrot code wrapping the C library and calls the functions you want, and wrap all of this again in some nice Perl 6 module/class. I believe that the plan is that Pugs will be re-written from Haskell into Perl 6, so writing your binding to the C library with Haskell's support for doing so probably won't be a long-term solution to your needs. Hope this helps, and corrections welcome (all(qw/beer wine baileys/) == none(@good_idea) ;-)). Jonathan
