One thing I noticed: you work with tail pointers for consing stuff
together.  Don't.  For one thing, they are a non-Guile data structure
and thus are shaky with regard to garbage collection.  For another, they
make the code look more complex.

And most importantly, they are _slower_ than just consing a list
together in _reverse_, then reversing it in one go using scm_reverse_x.
I profiled this.
