Interesting idea. I have a few questions though:
* Will it be fast? Are you going to be compiling to machine code, or
interpreting? Or both?
* Will it be secure / modular / sandboxed? You mention Namespaces; does
that mean that the machine would be safe to run foreign code? Is this a
Also, a more general question. There are no instance variables and you
can only assign to them by doing #instVarAt:...
Now, this is a great idea, but will you be making "a := 2." shorthand
for "myObject #instVarAt: 4 put: 2."?
What happens in Squeak? I see instVarAt:put: in class Object, so does
that mean that ":=" get's turned into a "instVarAt:put:" by the
compiler? Is ":=" considered to be a message? Much in the same way, is
accessing an instance variable turned into an "instVarAt:" by the
compiler? This behaviour would be very handy; you could do useful things
like adding pre- and post- conditions to instance variable usage by
overriding these methods.
p.s. congrats for getting into Georgia Tech!
