There are 2 possible approaches I think: either the translator defines the
whole set of specific functions which are necessary for the indexing
structure(s) to work, or those operations are defines at Indexable level and
all the translator has to do is to convert an index to its indexable. And
then the indexing structure calls whatever operation it needs on the
indexable itself. My approach was rather the latter. What would prevent us
from going that way?
