Exactly this (plus a good standard library).

In space-physics we have decades of C (and fortran) libraries 
whose output has been thoroughly vetted.  When a measurement 
platform is traveling over 7.5 km/second it's wise to use codes 
with well characterized round-off, and that usually means using 
old software.

Since python is the de-facto language of science, there are 
students whose entire master thesis is making useful interfaces 
to these old libraries. From D, I can just call them. It's great!
