Exception handling in switch (Preview)

[Pablo Grisafi]

Dear experts
Tagir Valeev does not like the proposal and among other things suggests

>  return try { yield Integer.parseInt(s); }
>    catch(NumberFormatException _) { yield null; };
> }

Por que no los dos?
I do like the proposal, but also like the yield-in-try option Tagir
Valeev proposes
In fact, why can't we have yield in any block? That will give as
if-expressions, try-expressions and even simply block-expressions
int a = {
  var x  = ....
  var y  = ....
  yield x + y;
}

thanks for your time
