Good idea.

One thing to watch is that arrays in SRFI 231 (and I think in most other
Scheme array systems) are in row-major order.  Libraries like OpenBLAS
have no overhead for operating with matrices in row-major order, while
the original BLAS are written in Fortran and assume column-major order.

So perhaps a good start would be to develop a Scheme calling convention
and interface for the routines in OpenBLAS.  Then Schemes with a C FFI
could actually link and call the OpenBLAS routines directly, while
simple, relatively inefficient routines could be programmed in Scheme
for systems without a C FFI.
