Hello!

Consider this module:

--8<---------------cut here---------------start------------->8---
(define-module (foo) #:autoload (does-not-exist) (baz))
(define (chbouib) (baz))
(pk 'hello)
--8<---------------cut here---------------end--------------->8---

Trying to evaluate it fails this way:

--8<---------------cut here---------------start------------->8---
$ guile --no-auto-compile t.scm 
Backtrace:
In ice-9/boot-9.scm:

[...]

 292: 3 [get-global-definition-hook baz (hygiene foo)]
In unknown file:
   ?: 2 [module-variable #<directory (foo) b3b510> baz]
In ice-9/boot-9.scm:
2732: 1 [b #<autoload (does-not-exist) b3b3f0> baz #f]
In unknown file:
   ?: 0 [scm-error misc-error #f ...]

ERROR: In procedure scm-error:
ERROR: missing interface for module (does-not-exist)
--8<---------------cut here---------------end--------------->8---

... which defeats the whole purpose of autoloads.

What about something along these lines (untested)?
