Gsubpy, an interpreter for subset of Python, written in Go

Recently, I write an interpreter for subset of Python using Go. I haven't seen source code of CPython, all is just written according to my understanding of Python so there may be some unusual things. Hope you can play fun with it. Any suggestion is welcome, glad to get some feedback.

In plain words

Gsubpy is an interpreter that executes a subset of Python code, built from scratch in Go. Created by an independent developer without reference to CPython's source code, it implements core Python functionality based on the creator's understanding of the language. The interpreter is designed for experimentation and learning, with the creator acknowledging that implementation details may differ from standard Python and welcoming feedback for improvement.

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
