I've begun to study language implementation. I've a long way to go and certainly will not be much help with the Perl6 effort... I wonder if you know about: The Stalin Scheme compiler? The realtime generational GC in rScheme? The very fast virtual machines of librep (aka Sawfish) and Guile scheme? I wonder if one of those VM's could be used (as is or with collaborative modifications) as a target for Perl6? -- mailto: (Karl M.
