Extracts only the bin/ files from the gem into the gem directory. This is used by default gems to allow a gem-aware stub to function without the full gem installed.

Uninstalls gem spec
Display a warning on stderr. Will ask question if it is not nil.

Used for stable sort via indentation level
Ruby’s sort is not “stable” meaning that when multiple elements have the same value, they are not guaranteed to return in the same order they were put in.
So when multiple code lines have the same indentation level, they’re sorted by their index value which is unique and consistent.
This is mostly needed for consistency of the test suite
Opening characters like ‘{` need closing characters # like `}`.
When a mis-match count is detected, suggest the missing member.
For example if there are 3 ‘}` and only two `{` return `“{”`
Pipes come in pairs. If there’s an odd number of pipes then we are missing one
Discards any changes that have not been committed
