Python - Idea 'Code Anchors'

Ingredients:

• Set variables to read only mode:
  • Unluckily cannot be done, the only work around is with deep-copying or removing the setattr of each variable.
  • Or maybe create a decorator like @assert_function_is_pure
• OPTIONAL: no need to pass locals() every time with inspect
• Understand how to create a “with” command:
  • Geeks for Geeks
  • Other Source
• How to create a new python-keyword like “assert”:
  • GithHub
  • # PEP 339 — Design of the CPython Compiler
• Add functionality to the IDE (Sublime Text) to support the use of code anchor, specifically when creating a new block of code i want to see the original code I’m working with, the code should be more gray-like and it shouldn’t be possible to change it.
