This seems to good to be true. Could one use this approach to gain
complete access to LAPACK or to the Numerical Recipes software? Or is this
something that one can do in theory but no one does in practice? I'm
looking into using Ada for numeric programming, but I'm disheartened to
find that there is very little supporting code available. Is this because
it is very easy in Ada to access existing functions in such packages as
LAPACK?
