Add `symtable.py` from 3.13.5 by ShaharNaveh · Pull Request #6048 · RustPython/RustPython

Walkthrough

The changes update the symbol table module in the standard library. The module's registration key is renamed from "symtable" to "_symtable". The PySymbolTable class is refactored to use property getters instead of explicit methods, adds symbol table constants, and removes or renames several methods to align with Python conventions.

Changes

Cohort / File(s)	Change Summary
Module Registration Key Update `vm/src/stdlib/mod.rs`	Renamed the symbol table module registration key from `"symtable"` to `"_symtable"` in the standard library initialization map.
Symbol Table Refactor & Constants `vm/src/stdlib/symtable.rs`	Added symbol and scope constants reflecting CPython internals; refactored `PySymbolTable` to use Python-style property getters instead of explicit methods; removed methods like `lookup` and `has_children`; added new properties including `id`, `nested`, `children`, `identifiers`, and `symbols`; changed method signatures and names for consistency.

Poem

In the warren where symbols dwell,
A rabbit hops with tales to tell.
Properties bloom where methods once grew,
Constants abound, all shiny and new.
"_symtable" whispers with pride—
Refactored and tidy, with nothing to hide!

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
