A lot of MTK is badly formatted. I'll PR after this to get it all in one go.

A lot of MTK is badly formatted. I'll PR after this to get it all in one go.

Just a suggestion, there was at least one JuliaFormatter release (maybe v2.0?) where people were reporting that it actually reformatted code in a way that introduced bugs into code (domluna/JuliaFormatter.jl#878). So if you do a mass format you might want to carefully review the changes to make sure they are sensible and not breaking code.

Thanks! I didn't know about that, but will definitely review the formatted code.

[ChrisRackauckas]

That was solved months ago though, is there still a relevant case?

[AayushSabharwal]

It seems a little unlikely. Somehow we didn't hit any of it despite actually running formatter regularly around that time frame.
