Closure required to no return statement

[cs278]

Bug report

This problem has appeared in 1.11.2, I strongly suspect it's related to #11092. PHPStan now seems to be able to infer that the closure will never be used therefore I don't need a return statement in the closure. This warning seems to be thrown from level 3 upwards. Like the previously mentioned issue I don't know if this was intended or an unexpected side effect of changes.

Expected output

No errors reported.

Did PHPStan help you today? Did it make you happy in any way?

Allows me to refactor with confidence.
