This is great. 

I’m wondering if it is possible (or sensible) to use pypy/rpython JIT generator?

Hey everyone,

This looks pretty nice. Playing around with it a little, it was
really cool seeing the original Self VM files load. I tried to
get a mirror via `object asMirror', but it seems like `_Mirror'
isn't implemented just yet. :)

Your AST parsing looks pretty well done. It actually looks like
my first attempt at a Self interpreter, only with less memory
management stuff :) I'm curious to know whether you would want
to switch to a bytecode interpreter in the future or keep it as
a pure AST interpreter for ease of understanding.

As far as I can tell memory management/GC is a non-goal to keep
the interpreter fully portable. Is this correct?

I checked out the GUI and it's already pretty nice as it is.
Buttons could benefit from being less... large :), but it's
already really usable (and more of a GUI than I came up with).

Also, do you intend to maintain full compatibility with the
original Self and its Transporter system, or are you willing
to improve upon it later down the line?

Hoping you decide to continue this project and looking forward
to further developments!

We began developing this system since the Self virtual machine is currently unable to be easily run on most modern operating systems (without setting up a virtual machine to emulate older 32-bit operating systems).

The system comes with its own GUI framework to demonstrate its features that is extensible by users, and the framework itself serves as a proof-of-concept for implementing Morphic-related features in the future. The interpreter’s implementation is bootstrapped, meaning that higher-level features like lists and strings are directly imported from their respective Self modules, which we file out from the original Self system.

If you’re interested in exploring our system further, we’ve prepared a video demo for your convenience (here). You can also visit our repository on GitHub below.
