No need to invent syntax, this proposal was part of the language
design at one point, but was removed as being an excessively
complex feature for too little gain. There were even conditional
expressions to use in this context.

Matthew, as someone who is always feature hungry and always
wants more complexity in the language, you should definitely

of bells and whistles you found there :-)
