This one is (technically) closed by that pull request.\r\n\r\nAbout the primitive interface... Initially I though there would be _some_ minimal interface, but it turned out that nearly every procedure can be implemented more efficiently in C because of the intimate knowledge of bignums. So the Scheme part of the library would be very thin (like, variadic handlers for associative operations, and maybe `bitwise-not`)."}}
