I think it's good. I have just taken the liberty of committing your
version, with two changes: I have added @xref{Sequences Arrays Vectors}
at the end of the first paragraph. I have changed "return" to "returns"
to indicate that the "returning" is mandatory, and not a subclause of the
"can" bit. (A small point, but I think it's more correct.)
