Sure, the exact syntax is a matter of discussion, I just wasn't that much of
favor of the very short
doSomething(with: myOptional?)
- it looks like a great idea, making the code really short
- on the other hand the question mark is next to the variable, but the method's
execution is optional - in that sense something like doSomething(?:
myOptional)(with: myOptional) makes more sense, declaring explicitely what
optionals does the execution depend on.
- nevertheless, in the interest of clarity and readability of the code, I'm
still in favor of the original proposal, which requires you to either use if or
guard.
