Comment (by ncohen):
> Still about the naming... Compare to #19123. These are kind of same
thing, but for lattices it is more natural to think about making the top
element of lattice 1 and the bottom element of lattice 2 to one common
element.
What do you want us to compare in the naming of this function and the
content of #19123?
> A suggestion: What if I only make a function whose name starts with `_`?
Then we could use the code to build more functions, and think later about
the name.
Then that means that the function will not appear to the users, and that
we will not even use it ourselves at the moment. I don't see the point.
