@mjtsai I can see the value in macros like that. But I don't see a way to do that in Swift. Or rather, that doesn't fit with The Swift Way.

@mjtsai And about the adding a `!` after each variable use, have you considered implicit unwrapping?

@roopeshchander That's discussed in the comments.

@mjtsai Just saw that. On second thoughts, it's better NOT to use implicit unwrapping here, coz we need to check for nil. if-let is better.

@roopeshchander Choice between compiler help with safety and avoiding extra indentation.

@mjtsai We can't avoid the extra indentation because `if` is unavoidable, right?

@roopeshchander Right. That's why I think there needs to be a better way to do this in Swift.

@mjtsai @mjtsai I don't think an `if` block by itself makes it bad-looking code.
