Consider avoiding the use of powershell anti-pattern "return $foo"

As per:

While return accepts explicit retvals, it should only ever be used in naked form for exiting a function early. Returning a value is considered an anti-pattern in powershell because it gives the impression to people unfamiliar with the language that return is the only way to return values, when the reality is that any non-captured output is returned.
