One that uses lots macros, and rely on heavy uses of EVAL -- far
more than I would like.

If ECL, when compiled in profile mode, had the ability to link
programs statically,  even though when configured with
--enable-shared, that would not be much trouble for OpenAxiom.
But given the build time and the implication of restructuring
the build system, it is a bit of undertaking...
