:+1: on using `Option` instead of a guard func & null. Looks nice and clean to me.

Maybe i should add fold3 to [these](https://github.com/fantasyland/fantasy-these/blob/master/src/these.js#L8) 😄

I bet @puffnfresh wouldn't mind donating daggy to fantasy-land tbh.

Having used `chainRec` a few times now, I wish we had used `Either`. I'm not totally sold on a whole spec for either as they type should say enough?

Thanks @safareli some food for thought :+1:

As always @joneshf you put it way better than me...

I found it very informative 😀
