For those not very familiar with Scheme, the sequential notation will be
significantly more readable.  For those familiar with Scheme, it should
be trivial to learn.  Wouldn't you say it's worth it in the long run?

And just to chip in my personal opinion, I find the deeply nested and
reverse notation to be fairly ugly. :-) The notation I propose builds on
the idea of a pipeline, which is still purely functional, and I suspect
it's more intuitive to most humans even if they know FP well.

Indeed, I agree.  However, I think these are simple enough macros, such
that if the manual just shows with an example what their use expands to,
it should be enough for those interested to quickly grasp it.
