Yes. Right now, whenever i stumble upon a usefull but undocumented
part of the Guile API i'm somehow reluctant to use it since i fear
that it's not as stable as the documented part.
Who to consult in such a case? Guile-devel or Guile-user?

Yes, i would assume that it's up to those who write the documentation
for guile-embedding applications to provide helpfull intros/tutorials.
After all: most general Scheme tutorials will present things like
'my-fact' or 'is-prime?' while users probably want to read about
'print-in-blue' or 'image-blur' ....

Ok, next time i find one ...
BTW, in case i have a documentation patch: where to send it to?
Post it here?

Finally, a proposal: I think it would be rather helpfull if the
documentation for C functions as well as CPP makros would include
the type specifier. So, instead of:

 scm_make_vector (k, fill)

give

 scm_c_make_vector (unsigned long int k, SCM fill)

Not having the parameter types is sometimes missleading, esp. if
the same parameter name sometimes stands for a C value and sometimes
for a SCM value (see for ex.: 'scm_vector_set_x vector k obj',  where 'k'
stands for SCM value).
I'm willing to take over that job and update the relevant parts over
the next few weeks if people find this helpfull.

Thanks,

    Ralf
