Andy made it clear that it was a bug.  There’s an interest in providing
a good bootstrapping story for Guile; that’s why there’s an interpreter
written in C, for example.  I’m sure we’d be happy to address psyntax
bootstrapping as well!

Sure, we can discuss the details of how to integrate your code.  (Guile
incorporates code not initially written for Guile, such as sxml or
(ice-9 match), and the policy is to not require copyright assignment for
such code.)

Yes, that would be great.  We’ll have to take a closer look, but I’m
under the impression that a fruitful approach for Guile would be to have
it maintained in-tree; that would immediately benefit all distros.

Thanks!

PS: Not all GNU packages require copyright assignment.  Guix doesn’t,
    for instance, and we’d be happy to get your contributions.  :-)
