how do I test that a function returns nothing when called in void context?

Two thoughts:

  1. Why would it matter?

    If a function returned a value in a void context, it is just discarded.

    Not returning anything in a void context is not the point, it is not calculating the return values if they are never going to be used that makes a difference.

  2. Testing something that is obvious by inspection is a waste of time.

    If the first line of the sub is return unless defined wantarray;, the sub will not return anything when called in a void context. There is no need to test that.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
