Do not agree here. Named macros are not understandable by machines ... 
except if the human associates with the macro a formal description that 
algorithms can deal width.

Macros might even be misunderstood by humans, even if the macro comes 
with a very carefully written description in English. Only languages 
with well defined formal semantics allow to express things w/o ambiguity.
