PangoWeight is an enum, so you should be able to simply use the nickname 
strings:

  $renderer->set("weight" => "bold",
                 "weight-set" => 1);

As long as we don't have a documentation viewer for the introspection 
stuffÂ, your best bet is to look into the .gir file, in this case 
<prefix>/share/gir-1.0/Pango-1.0.gir.  There you see how 
gobject-introspection interprets the C declarations, and this will map 
almost always one-to-one to Perl.

And for enums of course, the usual Glib magic applies.  See 'perldoc 
Glib' â PERL VERSUS C â This Is Now That.

 Writing a documentation viewer would be a worthwile project, I think. 
 All the information is in the .gir files, including documentation.
