Hi!,

Was surprised to see GST placed after Lua and a host of other
interpreters in the language shootout. I always felt that GST was one
of those faster VMs.

First of all, 2.2 was faster. Secondly, remember that Lua and Python and Perl execute mostly C code for the data structures. Once you start writing your own objects and not only use associative arrays, GST will be better.


Also, GST has a JIT compiler though I don't know if it can run all the tests in the shootout (bugs).

How is the VM implemented ? Is it a stack machine ?

Yes.

Does it use a tagged representation ?

Yes.

PS: is there a *working* mailing list so that I dont keep
posting/bugging you all the time ;) ?

Yes, help-smalltalk on http://lists.gnu.org (I've CCed it). Even if you do not want to subscribe, you can CC it (it is open).
