If we do this, we should contact the various other projects to make them 
use (ice-9 base64).

I think it would be simpler though to consider the base64 in 
guile-gcrypt to be 'canonical', it would avoid problems with old 
versions of Guile not having the base64 module and newer version having 
it, which would prevent using the proposed (ice-9 base64) in Guile 
because it would break build-aux/build-self.scm when pulling or 
time-machining from old Guix that have an old Guile.

Whether we simply replace (guix base64) by (gcrypt base64) depends on 
how old (gcrypt base64) is compared to the earliest 'supported' Guix for 
pull/time-travel, but even if it is not present in the old gcrypt, we 
can work-around that (we have a 'fake-gcrypt-hash' in 
build-aux/build-self.scm, so we can easily have a (define gcrypt-base64 
[some copy])).  Or simply update the local guile-gcrypt in 
buid-aux/build-self.scm.

OTOH a similar replacement can be done for (ice-9 base64), but 
transitioning to (ice-9 base64) would take much longer, at least until 
the various distributions are updated to a Guile that has (ice-9 
base64), whereas (gcrypt base64) could be switched to immediately.

Maxime.
