Well, yes, it would be copied to the local stack once func() returns,
but the problem is, for how long.  It may be that the current
implementation in dmd keeps that stack location allocated until the
function returns, but it would be equally valid to reuse that stack
location after the expression is over, because by definition, rvalues in
the expression would have gone out of scope.
