I'd gladly author an enhancement once I'm certain of what exactly to 
state in it.

Always optimizing return foo(args) to a jump may have impact on 
debugging experience (curious call-stacks) and cost people hours of 
wasted time chasing shadows.

Adding an explicit form for it seems to me far more appealing and honest.
