This is probably fine, but you might also want to try the
scm_c_module_lookup function(s).  They should be a little bit more
efficient:

     SCM proc = scm_variable_ref(scm_c_lookup("eval-string-from-file"));

There's also a SCM_VARIABLE_REF macro.

Actually it looks like there is a scm_call_4.

It could be worth adding something like this to Guile, but I'd need to
think a bit more about what might be most generally useful.
