Maybe a note could be added to

Something along the lines of:
Note: If exec gets two separate objects as `globals` and `locals`, the code
will not be executed as if it were embedded in a function
Quentin Peter added the comment:
Thank you for your explaination. Just to be sure, it is expected that:
exec("a = 1\ndef f(): return a\nprint(f())", {})
Runs successfully but

The reason I am asking is that I am working on a debugger. The debugger stops

Peter Tillema added the comment:
Right, I should have clarified it a bit more. I'm using NumPy arrays because
they allow indexing like this, where the input arguments are converted to a
tuple. So
a[1, 2, *[3, 4]]
is different than
a[[1, 2, *[3, 4]]]
This indeed only works on NumPy
New submission from Peter Tillema :
It would be nice if you could starred expressions in list indices, for example
this piece of code:
```
import numpy as np
a = np.array(0)
print(a[1, *[2, 3], 4])

Every piece of code that uses either lib2to3 or a parser derived from it
(including parso and LibCST) will eventually not be able to upgrade the parser
