Good idea.

I've made a start here: https://github.com/hlorus/CAD_Sketcher/pull/425

It now only removes constraints that are actually new. If the sketch fails, it removes all of the new constraints. Ideally it'd find out which constraints specifically are conflicting and...

Oh and would it be possible to set the linter to 120 line length? That'd be consistent with the actual code base, so it would stop failing every time.

If you think the context manager is good now, I can start adding the other operators yeah.

I could use some help coming up with cases where auto constraints fail actually. It's easy enough for line_2d, but other than that I'm not sure.
