JSIL and embind both need arguments.length for efficient method call
dispatch when dealing with overloaded functions. Is it your intent
that all such scenarios must now pay the cost of creating an array (to
hold the rest arguments) and then destructuring it, for every call? At
present it's possible to avoid this overhead in V8 and SpiderMonkey by
using arguments.length + arguments[n] or by using arguments.length +
patterned argument names.
The array created by rest arguments has no reason to cost more than the
arguments object. It's only an implementation concern.
