Summary -- This PR fixes the issue pointed out by @JelleZijlstra in https://github.com/astral-sh/ruff/pull/17101#issuecomment-2777480204. Namely, I conflated two very different errors from CPython: ```pycon >>> def m[T](x: (yield from 1)): ... File "<python-input-310>", line 1 def m[T](x: (yield from 1)): ... ^^^^^^^^^^^^ SyntaxError: yield expression cannot be used within the definition of a generic >>> def m(x: (yield from 1)): ... File "<python-input-311>", line 1 def m(x: (yield from 1)): ... ^^^^^^^^^^^^ SyntaxError: 'yield from' outside function >>> def outer(): ... def m(x: (yield from 1)): ... ... >>> ``` I thought the second error was the same as the first, but `yield` (and `yield from`) is actually valid in this position when inside a function scope. The same is true for base classes, as pointed out in the original comment. We don't currently raise an error for `yield` outside of a function, but that should be handled separately. On the upside, this had the benefit of removing the `InvalidExpressionPosition::BaseClass` variant and the `allow_named_expr` field from the visitor because they were both no longer used. Test Plan -- Updated inline tests. |
