Conceptually, yes, but if you take into account the details of how you
specify which element you want, as well as what you want to do with it,
then in most cases, I think the code ends up just as simple with
seq-some as with seq-find.

And using seq-some doesn't have the weird nil corner case.
And defining seq-find as I did means it's always less efficient.
And defining seq-find more efficiently means code duplication.
