Because it already exists? E.g. most BLAS/LAPACK functions are pure;
should they be re-written in Haskell?

[Yes, I know that BLAS/LAPACK are written in Fortran, but I don't
think that changes the argument. The resulting object code (which is
what you would actually be using) wouldn't be significantly different
if they were written in C.]
