It appears that trying to assign a variable to itself is an error: var foo = 5 foo = foo // error: assigning a variable to itself
However, I was thinking about this and was wondering why this is an error and not a warning. If, for example, the assignment had a side effect (e.g. a didSet block) I’d think it would be warning, possibly ignorable with a set of parentheses. Thoughts? Saagar Jha
