Re: Questions with embedding guile

unfortunately, it looks like `gh_eval_file()' uses
`scm_primitive_load()', guts excerpted:

:  {
:    SCM form, port;
:    port = scm_open_file (filename,
:	     scm_makfromstr ("r", (scm_sizet) sizeof (char), 0));
:    while (1)
:      {
:      form = scm_read (port);
:      if (SCM_EOF_OBJECT_P (form))
:        break;
:	scm_eval_x (form);		/* <-- return value lost */
:      }
:    scm_close_port (port);
:  }
:  return SCM_UNSPECIFIED;

the value of the evaluated form is lost.  you can probably save that
value and return it.  i wonder why this is not the default?  (is this
related to the "strong differences in opinion among implementors"
alluded to in the guile-ref Info-page?

anyway, in case anyone is interested, a patch to libguile/load.c
follows.

regards,
