I thought I could differentiate between the parameters and the instance variables using self.variable vs just variable.
The ambiguity isn't on the left side of the assignment. That is clear enough with the dot syntax. The problem is on the right side, where a plain, unadorned "label" could be an attempt to reference the parameter or the instance variable.
Dot syntax is one way of accessing your properties, but not the only way. The lack of dot syntax doesn't make an identifier fail to match an instance variable.
