Except with method extension, where, to my knowledge, no-one 
has managed to write a computer program to find valid 
extensions that properly follows the criteria in the 
decisions.  Specifically, the requirement that the extension 
must cover on an indefinite number of stages is problematic.

Making it difficult to write tools is one thing; making it 
so damned difficult that no-one has any idea how to do it 
without making possibly-unjustifiable assumptions is quite 
another thing.
