# Zag-Smalltalk

Smalltalk VM Written in Zig with methods stored as type-annotated ASTs

Methods are re-constituted from the AST for edit windows. 

No Interpreter; uses Threaded and CPS execution models interchangeably 

Memory structure and some of execution principles loosely modelled on OpenSmalltalk VM 


Eventually it wiil include a JIT compiler

(Previously called AST-Smalltalk, but since the implementation is in Zig, a rename seemed obvious.)
