Jost, I think it's, like, totally obvious that thi is talking about
the present Guile module system, and, moreover, about *using* it.

this implies a certain meaning of the word "interface" which is not
the meaning you give above.  the definition you give is true if you
are talking about some other module system.  it's also kinda true if
you are talking about the *implementation* of the current Guile module
system (I'm not sure about that, though).

but it's absolutely irrelevant in the context of this discussion,
since "interface" as you define it is not really a user-level concept
of the current Guile module system.

different, but not ortogonal.  both these things control visibility of 
bindings.
