And sadly it breaks. It will likely take me some time before I can look into this though.

No worries. I haven't come across any issues so these might be a few corner cases, and only on 3.11 https://github.com/MatthieuDartiailh/bytecode/actions/runs/8344140634/job/22835903388?pr=143
It is nice to see that 3.12 is fine !
Maybe something to look into is why it seems to take about twice as long on 3.12 to recompile about the same number of code objects
Recompiled 11901 code objects in 0:00:48.426503
Compared to what ? 3.10 ?
To me that is not that surprising due to the introduction of exception tables in 3.11.
3.11 took 36s (I think we can assume it re-compiled all code objects without errors). 3.10 and earier are all in the ballpark of 25s. It makes sense for 3.11 and later versions to take more time because of the extra data structures, but the exception table is generally much smaller than the bytecode itself, so I don't know if that alone can really explain a 100% run time increase. I'll see if I can get some CPU profiling data
@P403n1x87 did you ever manage to generate the profiling data ?

@MatthieuDartiailh the tests on 3.13 pass without the re-compilation. It looks like the wrong arguments are being resolved. I have added
print("availabe_services", available_services)
and these are the results
unit/test_session.py availabe_services Session(region_name=<Mock name='mock.get_config_variable()' id='4875256224'>)
Favailabe_services Session(region_name=<Mock name='mock.get_config_variable()' id='4875263280'>)
unit/test_session.py availabe_services ['good-resource']
.availabe_services ['good-resource']
@MatthieuDartiailh I have the feeling that the CFG needs a similar fix to #145
assert te.entry is self._current_try_begin
WDYT?
Superseded by #149
We improve the logic for round-trip re-compilation of code objects by listening for module code objects before they are executed. This way we can thoroughly recurse over nested code object and attain total coverage for better confidence.
