> What is your evaluation of the proposal?
I don't like "form" as a prefix. To me there is no difference between `union`
and `formUnion`: both sounds functional-style, and actually the second one
perhaps a bit more to my ears. There's basically two dictionary definitions of
"form":
1. "bring together parts or combine to create (something)" which to me implies
a new value is created, and
2. "make or fashion into a certain shape or form" which would imply that the
material you start with is transformed, which is apparently the intended
meaning and also the reverse meaning from the above.
I mean, doesn't this make sense as an API?
let donut = baker.formDonut(dough) // non-mutating
Perhaps instead of "form" we could use "become" as a prefix when the operation
is naturally described by a noun. That would seem less ambiguous to me:
a.becomeUnion(b)
a.becomeIntersection(b)
a.becomeSuccessor(b)
It's a bit passive, but I find it fits well when the operation is a noun.
And there's no way the term lends itself to non-mutating cases without things
becoming nonsensical:
let donut = baker.becomeDonut(dough) // non-mutating?

I'm still not entirely convinced any of this is better than the `InPlace`
suffix we had before. `InPlace` might be ugly visually and grammatically, but
seems to be the clearest at expressing the intent.

There is no question that using a verb instead of the `InPlace` suffix makes
things fits better with the other API guidelines.

Read the guideline and API diffs, thought about a few alternative wording,
looked in my dictionary.
