Comment (by pbruin):
Replying to [comment:1 SimonKing]:
> By definition of categories C, for each pair of objects A,B of C, the
morphisms in C from A to B form a set. So, it seems very odd to me that
homsets of schemes currently aren't sets.
Yes, something in the category framework is preventing
`Schemes().Homsets()` from being in `Sets()`. It seems possible to fix
this by just deleting some code (see the branch and
:comment:26:ticket:15618).
