Rather than splitting up the function it might be possible to insert these into the front of function.block.stmts.

Might need to assign the argument back out:
| let (_, e) = #pyo3_path::impl_::pymethods::inspect_type(#ident); | |
| let (#ident, e) = #pyo3_path::impl_::pymethods::inspect_type(#ident); |
(I think this would matter for edge cases where the module is using Bound<'_, PyModule> or Py<PyModule> for some reason, and inspect_type would transfer ownership rather than copy.)

I think this is ready now, and it actually found a few placed that we haven't updated yet, including two doc tests 🎉 |

Great, many thanks!
I'm sure there are quite a few more GIL Refs sneaking around various edges of the codebase... Hopefully we can eliminate a few more from the docs before 0.21 final. The road to 0.22 is littered with removing most of the rest of them PyO3's test suite, I think 😂
This uses the framework of #3847 to deprecate
&PyModuleas#[pymodule]argument type.This is done by modifying the original module function on macro expansion and injection of the gil-ref extractor with deref specialization. This can (and should) be reverted once the gil-refs are fully removed.
I assume this will need some tests, I will add those if we want go with this
