If it helps you in the short term, please feel free to look at
patching those modules so that they use a prefix that doesn't end with
a colon.  I think that should be compatible in API terms, because the
prefixed names are only used internally within the using module.

That sounds very tricky!  As Ludovic said, I think read options need
somehow to be less global - whether via Guile-Reader, or otherwise.
