Comment:
1. The growth elements call `self.parent()._var_.variable_names()`. I am
wondering why they do not simply call `self.parent().variable_names()`.
2. Why can't a generic growth element decide on its own? It could simply
call
{{{
if self.is_one():
return tuple()
else:
return self.parent()._var_.variable_names()
}}}
which would probably end in a desaster if called on a generic growth
element, but we are not supposed to instantiate generic growth elements
anyway ...
The rest is fine for me.
