Spec: https://www.openacc.org/sites/default/files/inline-images/Specification/OpenACC-3.1-final.pdf

In Section 2.16.2 it says "If there is an argument to the wait clause, it must be a wait argument (See 2.16.3)."

Section 2.16.3/Page 80
```
The wait argument, if it appears, must be a wait-argument where wait-argument is:
[ devnum : int-expr : ] [ queues : ] int-expr-list
```
