The homogeneity and ease of use of SLALIB could perhaps be improved
in the future
by turning to C++ and object-oriented techniques. For example ``celestial
position'' could be a class and many of the transformations
could happen automatically. This requires further study and
would almost certainly result in a complete redesign.
Similarly,
the impact of Fortran 90 has yet to be assessed. Once compilers
become widely available, some internal recoding may be worthwhile
in order to simplify parts of the code. However, as with C++,
a redesign of the
application interfaces will be needed if the capabilities of the
new language are to be exploited to the full.
