You raised two hypotheticals and said you honestly don't know if either/both/neither are true.

1. Is it like Python generators?

2. Is it a bad example of design by committee and meant as a set of lower level primitives?

GP responded that 2 is correct (but without the sass on design by committee) and that 2 allows for them to implement such things as 1.

I think they gave their opinion as to what parts of your hypotheticals are true, and that is a valuable contribution, and very much not the same as just repeating parts of your comment ("I literally said this").
