I think licensing matters would make this difficult. What I do think we 
can do is:

(a) Provide standard data layouts in std.array for the typical shapes 
supported by linear algebra libs: row major, column major, alongside 
with striding primitives.

(b) Provide signatures for C and Fortran libraries so people who have 
them can use them easily with D.

(c) Provide high-level wrappers on top of those functions.
