In node 0.10, Map/Set size don't throw on Set/Map, respectively

[ljharb]

var setSize = Object.getOwnPropertyDescriptor(Set.prototype, 'size').get;
var mapSize = Object.getOwnPropertyDescriptor(Map.prototype, 'size').get;

setSize.call(new Set()); // 0
mapSize.call(new Map()); // 0

assert.throws(function () { setSize.call(new Map()); }); // should throw but does not
assert.throws(function () { mapSize.call(new Set()); }); // should throw but does not

This code passes on es6-shim, and in any engine with native Map/Set.

This is blocking expect and object-inspect, which affect a number of downstream projects. Any chance this could be looked at soon?

Thanks! What version will this be released in?

@ljharb sorry for the delay. I wanna fix some more issues and test it, so seems 2.5.0 will be released after some days.

Sounds good, thanks! I'll keep an eye out for it.
