I notice that the current draft spec says: >> The ExpectedArgumentCount of a FormalParameterList is the >> number of FormalParameters to the left of either the rest parameter >> or the first FormalParameter with an Initialiser.
This aligns ExpectedArgumentCount with built-in functions like Array.prototype.splice in specifying (more or less) the minimum number of arguments for the function to work properly. Leaving aside congruence with built-in functions, it seems like it would be more helpful to know the total number of formals, minus the rest parameter. Is there any other reason to favor the current semantics? Kevin
