I'm not sure I understand what you mean by multiple bindings? With if-let, binding to the variable is conditional, and it only happens if all parts of the chain

I'm not sure I understand what you mean by multiple bindings? With if-let, binding to the variable is conditional, and it only happens if all parts of the chain return an actual value. Otherwise, as soon as one returns null, a jump can be made to the alternative branch. Am I missing something?
