I hope that you aren't completely broken. :-)

Complicated, yes. I also tried to use Uniform Array, found some
problems, and felt awkwardness.  Some developers seem to agree that
Guile's current Uniform Array (Vector) has some issues and should be
revised.

Now I'm surveying other multi-dimensional array implementations. Not
so much languages have such a data structure unlike that I imagined. I
first found that GSL's Vector and Matrix is neatly designed, which
originates from C++'s valarray. Fortran can treat it easily. Perl and
Python guys are considering to add better multi-dimensional array
implementations to their new versions.

I'll hopefully send a summary about this again.
