Thanks, I'll take a look.

I don't think that tests like isConstructor(TypedArray.prototype.with) must return false should (and can maximally properly - depends on isConstructor implementation) pass in polyfills that should work in ES3 engines, I'll check the rest.

The same I could say about tests of typed array methods with the redefined .length on typed arrays - I'm not sure that it's required for polyfills since it will cause problems for some old typed arrays implementations. However, OK, I'll adapt it to this behaviour soon.

Remains only the change from #70 - I'll add it right not.

So I think that it can be added.

I'm happy to ignore those tests 🙂

Interesting, did older type array implementations not use a getter to access the internal length?

Once these updates have been released let me know and I'll get this merged!

I don't remember concrete examples, but I remember many different problems with it when I wrote a typed arrays polyfill many years ago.

Now I opened (randomly) FF20 and I see that, for example, Int8Array.prototype.length getter (they haven't common %TypedArrayPrototype%) does not work with Uint8Array instances, IE10 - it's a usual property, not a getter.

I once again appreciated the necessary work for the case of redefined .length on typed arrays - that requires changes in about a hundred of modules with testing / debugging in hundreds of engines (in many cases - manual) and anyway will not fix it in some old engines. I'll work on it, but not soon.

A change for #70 (TypeError instead of RangeError if the result length is more that MAX_SAFE_INTEGER) already added to the repo - but I don't think that required a patch release ASAP - it's almost impossible case for a real life. I'll publish a new release for some weeks, you could wait for it - but I don't think that it's required.
