Comment on attachment 285039 [details] patch I don't think this is right if you do: let foo = null; class A extends foo { } Shouldn't that also be a base class? https://tc39.github.io/ecma262/#sec-runtime-semantics-classdefinitionevaluation

My implementation is quite broken. This may be a bit annoying to refactor to make this work.

Heads-up that this has been reverted from ES2017 (and came in after ES2016) after a discussion at January's TC39 meeting. The spec revert was https://github.com/tc39/ecma262/commit/c57ef95c45a371f9c9485bb1c3881dbdc04524a2
