Oh yea... that also raises one intresting idea: reconciling java with scheme. Java semantics seem to me much, much nicer for MIMD (just intuitively, no elaborate argument). Java also seems like a plausible variation on what you'd get if you wanted to take a subset of Scheme and add declarations. It's object model is a little heavy and weird, but it's also pretty simple. So maybe one approach is a split store: thread-private storage for Scheme data; shared storage for java-ish objects. There'd be plenty of other benefits to using Java as "typed Scheme subset" besides threads, too. -t _______________________________________________ Guile-devel mailing list Guile-devel@gnu.org http://mail.gnu.org/mailman/listinfo/guile-devel
