It didn't look too bad. However, it's incomplete.

There's also Ingy's YAML.pm for Perl, which is also recursive-descent 
and looks pretty clean.

Plus, either _why's Syck library could be made into a plugin, or that 
his YACC grammar could be fed to SmaCC.

I think the plugin idea is probably the easiest thing to do (that is, 
leverage an actively maintained external library), but it's got the 
added annoyance of being a plugin.

Plus there's a bit of an "impedance mismatch" between the 
yyparse()/callback model of the library and the Squeak plugin model: 
we'd have to buffer the nodes and then later let Squeak iterate 
through them to build the document model.
