binary loadable files

[Keisuke Nishida]

Hello,

I'm considering how to store bytecodes in binary files.
I want to make it as general as possible, so that I can
store not only bytecodes but also any Scheme objects.

I'm thinking of the following procedures:
(Are there better names?)

  ;; Write OBJ to PORT in the binary format
  (dump OBJ [PORT])

  ;; Read an object from PORT in the binary format
  (pull [PORT])

If PORT is a file, pull will use read-only shared mmap
so that some memory can be shared between processes.

Since I want to store any objects, I'm thinking of adding
new slots `dump' and `pull' to scm_smob_descriptor.

Is that all good thing?  May I continue to work on this?
