Breaking changes for 4.1.0 behavior

It does look like transform-builtin-extend was not being applied. I published v4.1.1 as a fix.

Thanks for the prompt reply, verify the fix 🎇

Where is transform-builtin-extend you are talking about ?

I tried npm install @babel/transform-builtin-extend and npm install @babel/plugin-transform-builtin-extend but it didn't work

[bjyoungblood]

The package name on npm is babel-plugin-transform-builtin-extend (Github link). It's not owned or maintained by the Babel team.

Ok thanks bud @bjyoungblood

To finish on that topic, do you know if, nowadays, babel 7 is natively handling this correctly ?

(I have 2 apps, on with old school babel and one with pretty recent release, and wish I knew the status of this)

[bjyoungblood]

It looks like this was added in babel/babel#7020, but might not be bug-free yet (see babel/babel#7506).

FWIW, I tried compiling es6-error with Babel 7 (and no transform-builtin-extend). All the tests passed, and the output seemed to work fine under Node v9.9, but YMMV.

Ok thanks for your help ☺️
