    I can see that, but given the fact that it's only used interactively (where
    the performance impact is likely to be unnoticeable) or in gnus/deuglify.el
    and game/tetris.el, I think the that performance gains do not justify
    the pain and risk of writing and optimizing it in C.

I don't agree.
