Indentation sensitive parser combinators

An indentation sensitive parser combinator language is one that helps you express ideas like "this parse only succeeds if it's within the current indentation block". The concept is somewhat small and elegant and is implemented in a few libraries. In this writeup, I will use examples from indents.

Background and goal

The direct goal will be to write the sameOrIndented parser combinator with a type

GitHub RCE by Environment variable injection Bug Bounty writeup

Disclaimer: I'll keep this really short but  I hope you'll get the key points.

GitHub blogged a while ago about some internal tool called gerve:
https://github.com/blog/530-how-we-made-github-fast

Upon git+sshing to github.com gerve basically looks up your permission
on the repo you want to interact with. Then it bounces you further in
another forced SSH session to the back end where the repo actually is.
