I agree completely. There's no need at all to centralise
coercion, and most of the time it just gets in the way.

While you're at it, get rid of the special-case code
for number*sequence, which has the same problem. I once
implemented a matrix-like extension type, and I had
great difficulty getting it to behave like a sequence
for indexing purposes while having number*matrix do
what I wanted.
