Hello list,

I'm trying to create a Scheme function that will automatically calculate
and enact a *rall*. as a sequence of \tempo assignments. I am aware of the
basic *rall*., *rit*., and *accel*. functions in "articulate.ly" but I
wanted something I have a little more control over.

I need help, and I don't know if it's just in the implementation details or
my overall approach to the problem.

For now, it's just a *rall*. The algorithm describing the rate of slowdown
is extremely basic but that can be adjusted later.

My approach so far has been to create a list of values starting at 100
(let's assume percentages of the initial tempo and work that in later) and
then have them trickle down. Using #(display ...), I see this is working
just fine.

Clearly my \repeat call isn't appropriate here and I should replace it with
a recursive function call containing just its body (the {\tempo 4 = ...
\skip ...} part). And I'm sure I'm not really going to get anywhere with
#@tempi-list but I hope it communicates what I'm aiming for. I've been
playing with this for a few hours but I haven't been able to get the parts
to mesh together. I could keep stabbing at it, or ask for help here.

Code attached, and thank you!
