BTW: I originally thought to make Felix use Extlib,
since Extlib contains some data structures I want,
variable length array and PSet/PMap for example.

Unfortunately, these components are inseparable
because they're unified by the Enum concept,
and I have some issues with enums.

I also can't just reuse the parts I want,
since Extlib is LGPL and Felix is FFAU.
So I either use the package as a whole,
or don't use any of it (or make a subset
of it, package it separately, and use that,
getting the problems of *both* dependence
and loss of separate maintenance)

The point being: it is a fairly typical
problem that there is a tension between
separability and integration. In particular
it is precisely Enums which simultaneously
make Extlib components easy to use separately,
whilst at the same time making them all 
dependent on Enums :)
