Finish up LOAD_ATTR specialisation #100288

New issue
New issue

Description

We should target the following specialisation failures:

  • has managed dict
  • not in dict (how does this even happen??)

With these two we can hit >90% specialisation successes.
If we're feeling really ambitious, we could aim for "not managed dict" failure too. But we don't need that to achieve >90% successes.

I'm doing the first one. Is anyone interested in investigating the second specialisation failure?
