As with the Rust demangling (check the commit history, it was done earlier this year), I think this'd be easier to review if it were implemented incrementally - it'll be easier to spot the test coverage for each feature as it's added. Otherwise it's a lot of code to try to validate in one piece.

Thanks!
I suppose this won't be in the next patch release (10.0.1) but instead in the next major ?

Good to know, thanks! It's also my first time using arc, so I had to poke around a bit. In any case I didn't seem to include that whitespace fix even after squashing the commits together. If this is fine as is, then great.

Merge whitespace-removing commit into the main one

Add missing commit

Remove a trailing whitespace in TypeSystemClang.cpp

Remove un-needed main & use x86_64-pc-gnu as target instead of host

Changed the test from running to 'type lookup string'

Added Shell test

I wasn't sure what would be the best place / how to add an unit test for this. Could a reviewer provide some pointers ?
