oh, aaah. so thats why the constant wasn't working,
i was still trying to debug this last night but got
no further. i'm making these sorts of errors really
frequently so i'm gonna stick something in there
to print a list of matched classes on such failures
it'll make prototyping much faster. introspection as
a whole really needs to be improved actually, so 
DOM::Node.{constants,singleton_methods,new.methods}
etc should all work.

debugging in qtruby/korundum is a bit messed up 
atm as somewhere along the line i think a call_super 
was removed which was needed for proper error messages,
now even ruby errors such as variable name typos hit
the method_missing stuff in qtruby and the real error
is therefore never produced :( i'll fix this tonight
as its a pretty major showstopper :(

please see my branch on the korundum examples directory
for more interesting stuff, due to the freeze i'm unable
to commit to head for the coming weeks so i'll use the 
branch to develop examples.

cheers,
Alex
