schema[method] is not a function

I'm really hoping I'm not missing something simple. I could have sworn I got a simple example working after your most recent push (8727490), but now I can't get anything involving custom methods to work. Any schema with a custom method returns this error. I've inspected the yup module and the method is there, as far as I can tell.

Confirmed with yup ^0.29. This error does not appear when you use 0.28.x: https://codesandbox.io/s/naughty-ganguly-mszik?file=/src/index.js.

Edit: can't confirm with the unit tests though. Only appears with the production build so far?

Alright, so this took a while:

• When I install the yup-ast package via NPM, it breaks because yup-ast has the yup dependency installed inside of its own folder.
• When I use yarn instead; the package gets hoisted up and both use the same version.
• If they use different versions, the yup instance never gets the custom method, so you will have to provide your "custom" instance via the second argument (like so: transformAll([...], yup) to fix the issue.

Right now I don't know why npm does not link those two together, but, hey. at least there's a workaround?

Interesting. Yeah that workaround solves any issue. Another reason to just remove npm from my life entirely I guess.
