Heh. You wrote me a patch - now I feel bad. :) After reading your email I decided that I definitely should implement it (System.Time) through the FFI that's already there.

No need to feel bad, I enjoyed it and it only took me 10 minutes, it's also a bit of a tidy up in many ways. If you're adding things which are primitive parts of the standard prelude then I would recommend at looking at: - src/packages/yhc-base-1.0/YHC/Primitive.hs - src/runtime/BCKernel/primitive.h - src/runtime/BCKernel/primitive.c - src/runtime/BCKernel/builtin Some of the files in builtin are more closely tied to the runtime than others. Array.c, IO.c and System.c are fairly good examples of generic ones. Indeed System.c is probably the most sensible place for System.Time functions.

I'll try to find an excuse to use the make_ntuple. Thanks and kudos for the speedy response.

It'll be useful if you really need a function to return several different results, for example primIntegerQuotRem. However you don't need to try to use it ;-) Thanks Topm
