Gee, why did I think that Guy might have something to say here.  ;^)

Problem is Hal said he needed a solution that was 1.6-compatible,
therefore not relying on define_method...

Also, since the list of methods defined with 'build' is contained
in the keys of the @@dispatch_table, I don't see why method_missing 
would be objectionable here.  The trap could still raise a
RuntimeError if the method that led to it were not one that was
initially defined with 'build'...
