Note: if someone knows a way to include partial positions information as well as no position information (but only for a single instruction, and not for the entire code object otherwise we cannot test the -- rendering) by changing AST nodes only, please tell me.

The same way that dis tests '--' for line numbers should work. It inputs python code that gets compiled into something that needs '--'.

It inputs python code that gets compiled into something that needs '--'.

Mmh, yes it was dumb of me. I'll try this approach now.

The tests are a bit longer (in length) but at least I don't need some magical construction that I would forget about tomorrow :D Thank you all for the tips.
