How does it affect speed? One of the two purposes of sine is to be fast (the
other is to be bit-exact), and I am a bit afraid that the expression
evaluation is slow, even for constants.

Apart from that, no objection and LGTM, but I am not familiar enough with
the expr API to spot subtle mistakes.

And at some point it will be necessary to factor all this mess of
expressions.
