Honestly could see that coming up as an edge case with some very specific design where, like...
if statements are expressions and they implicitly evaluate to optionals if there isn't an else branch
there's a similar unless expression that functions as a negated if for convenience in, like, validating stuff or whatever, where the unless keyword and condition are postfixed to emphasize the value being validated
the unless expression is actually just part of the generalized if-else complex since it's all conceptually basically the same stuff
