If I understand you correctly, your idea is that the "return;" here would be
treated automatically as "return 'unknown';" I think that's an interesting
idea, although I can't immediately think of a situation where I'd use it.
My main concerns are with the syntax:
- Firstly, specific literals aren't currently allowed in return types, and
allowing them would have other implications. Three exception is "false", which
is allowed because of its common use as an error code, including in many
internal functions.
- Secondly, it could be ambiguous which is intended to be the default value, if
the return type was something like int|"yes"|"no"
Perhaps the default return value would need to be specified separately from the
return type somehow?

Hi Hamza,
Welcome to the list, and thanks for sharing this idea.
