This test now throws for its other issue of call violation, which is checked first in visit_Expr
. Hence, I removed it as there are already tests for call violation in this file.

There is an overlap here with #3546 (comment).

Another option here could be to check constancy of the context in _CreateBase.build_IR()
, similar to how it is being checked for raw_call
. However, this would not resolve #3546.

superseded by #3729 |
What I did
Fix #3554.
How I did it
Move the checks from
visit_Expr
tovisit_Call
. This causes semantic analysis to leak intoannotation.py
, but it should be fixed later on by #3456 when annotation and validation are combined into a single pass.How to verify it
See tests.
