I did something similar to check the requires clause of a lambda and it does technically fix the issue, i don't see a more elegant solution, but it does sound a bit wrong... (it allocates a dummy function scope that is then kept around forever)
Maybe we can add a fixme comment here and add a "remove lambda scope" with an raii object for these two cases in a separate PR?

The issue is not surprising though, there are weird order of operations in how parameters and functions and their context are handled.
