This kind of feels like “switch with a return value”, which might be a useful new construct, but I would advocate that if implemented, it gets a new keyword.  Maybe like…

	let x = pick(someValue){
	  	case <pattern1>: result1
 	 	case <pattern2>: result2
 	 	case <pattern3>: result3
 		default: result4
		}

but in practice, I’d be hard pressed to choose between this or something like making an array or dictionary of closures.
