I have implemented SRFI-10 and will commit the new module (srfi
srfi-10) in a few minutes.

Unfortunately I stumbled over a minor problem: Because ports are not
self-evaluating in Guile, not all examples from the SRFI document
work.  I think this is not really a Guile bug, because ports are not
required to be self-evaluating by any RnRS, AFAIK.  

But with a bit quoting magic, it is quite neat:

Example:

(define-reader-ctor 'file open-input-file)
(define f '#,(file "/etc/passwd"))
(read-line f)
=>
":root:x:0:0:root:/root:/bin/bash"

The more I work on this SRFI stuff, the more errors, bugs and
inconsistencies in the documents I fall over...
