Change looks good, testing it really quick locally before signing off..

return Reflect.construct(type, args, new.target || type);
const res = Reflect.construct(type, args, new.target || type);

if (this && !new.target)? Otherwise this would also set the prototype for cases like new Class(), right?

do you think the commit message is ok? or it should be tagged as util?

there was a bug in my test, and it is not working as expected, i.e. it is not fixing the bug :(.

I'm running a CITGM on this, it seems a little "breaky" (explicitly calling Reflect.setPrototypeOf(this, res);)

Updated. This is more controversial, so @addaleax @watilde you might want to recheck this.

Fixes internal/util createClassWrapper to support inheritance
without using classes. The constructor now needs to be defined
using a Symbol.

Fixes: nodejs#13358

Eh, yes, this is a bit icky. The code still LGTM but I think I might prefer just going back to using functions instead of classes instead…

I just checked it quickly and it works in node-crc32-stream as well, but I thought the same thing with @addaleax.

The fix is a bit unfortunate but it definitely makes sense in that this approach does essentially the same thing as the old function approach. @mcollina is away at the moment but I'm going through and seeing if there's a way of making the fix cleaner

In general... I think reverting back to using Functions is likely going to be the best bet long term... it is unfortunate, and is not going to be a clean revert... I'll work on that today
