[Iwan Vosloo]

Hi Tariq,

Nice work and good timing to share it here.

You might be interested to know about reahl-parseltongue [1], which 
covers similar ground and is used commercially on a number of client 
projects. Built on top of it is our own AI assisted experiment - 
Swordfish [2] - a GemStone IDE (that runs on for Linux too) with an 
integrated MCP server for AI-assisted development inside a gemstone 
database.

Regards,
Iwan
