I see that everybody is happily cleaning up these slightly odd theories
due to Robert Himmelmann, based on material from John Harrison.

Maybe I should try to improve the implicit "rule" method to reveal the 
rule that was applied --- via a form of semantic completion.  It is a bit 
more difficult than the other completions so far, because there is also 
the lazy enumeration of rules and rule instantiations involved.
