# 23 — General cleanup and refactor

**Status:** open

Housekeeping pass over the codebase.

## Function names

Function names should be reviewed and improved for consistency and clarity.

## Global namespace (`_G`)

Review what's exposed in `_G`. Do we need to expose everything? Candidates for cleanup:

- `__command` — internal, could be hidden
- `__interactive` — internal, could be hidden
- `__getenv` / `__setenv` — internal, could be hidden
- `__builtins` — should this be user-facing or internal?

Consider whether internal functions should live in a single `__lush` table or use the registry instead of polluting globals.
