I thought it meant "the parameter can be returned" not "the parameter *will*

And what about multiple `return`-qualified function parameters?
'return' means treat the return value "as if" it was derived from that
parameter. If multiple parameters are marked as 'return', treat the return value
as if it was derived from one of them.
This "as if" thing enables the designer of a function API to set the desired
relationships even if the implementation is doing some deviated preversion with
the data (i.e. a ref counted object).
