Hmm, dunno. I feel like many of Guile's users might be doing this. OTOH
they don't have `coding' support. I guess I can see your point here.

If scm_read() looks for the coding as a property of a port, I can
imagine it mutating that value too.

Why not allow scm_read() to detect this, and modify the port's encoding?
Apologies if I missed the explanation :)
