☔ The latest upstream changes (presumably #60969) made this pull request unmergeable. Please resolve the merge conflicts. |
Note that the `is_gensymed` call on `primitive_types` is unnecessary because that table only contains the name of primitive types (e.g. `i32`) and never contains gensyms.

It's a slight performance regression, but I think it's necessary to take at some point in order to move gensym-ness away from symbols. We've had a bunch of significantly larger performance improvements related to symbol handling recently, which more than make up for this. @bors r=petrochenkov |
