The macro solution they went with is the only one I know of that is as easy to use as exceptions without the associated baggage.

I didn't know about Swift, thanks for the link.

I left out Haskell on purpose - do notation can do "anything" for certain values of "anything". Then people stack monad transformers 4 deep and I'm off to the hills. Or would be if I wrote Haskell, there's a reason I don't.

Hey...let's just go crazy, and borrow some bew syntax from the .net team (bang..bang !!)

// don't ask me what this would do... I don't care.
if( toInt("123")!! + toInt("abc")!!)
{
   writeln(ex.msg);
   return -1;
}

Seriously, when will this obsesssion with constantly changing languages..stop!

D... plz learn the lessons from the silly .net team... I no longer even recognise C#
