Required prerequisites

• Consult the security policy. If reporting a security vulnerability, do not report the bug using this form. Use the process described in the policy to report the issue.
• Make sure you've read the documentation. Your issue may be addressed there.
• Search the issue tracker to verify that this hasn't already been reported. +1 or comment there if it has.
• If possible, make a PR with a failing test to give us a starting point to work on!

Describe the bug

from itertools import product
import cudaq

@cudaq.kernel
def test():
    q = cudaq.qubit()
    x(q)

does not work...

Expected behavior

no error

Is this a regression? If it is, put the last known working version (or commit) here.

Not a regression

Environment

• CUDA-Q version:
• Python version:
• C++ compiler:
• Operating system:

I'm using CUDA-Q container for 0.9.1

Suggestions

import itertools

is ok. (workaround)

from datetime import datetime
import cudaq

@cudaq.kernel
def test():
    q = cudaq.qubit()
    x(q)

does not work. It seems that from X import Y is not ok (?)

I suspect this is related to #2531 as well
