Hi Andy, Thanks for hacking on Guile-VM! :-)
As I mentioned yesterday on IRC (but you weren't there), I was just slightly skeptical about the move from `match' to `pmatch' + `record-case', but that's something I can live with. And the rest looks cool. ;-) (I don't have much time currently to do more than gratuitously comment the changes...) Cheers, Ludovic.
