With the current `Transform` API, transformations are applied to the left-
hand side of the lookup only.
For instance, if you define some unaccent `Transform` performing the SQL
operation `UNACCENT(...)`, the query below won't return an `Author` with
first name Jérémie. Actually, it won't ever return anything.
{{{
Author.objects.filter(first_name__unaccent__iexact="Jérémie")
}}}
I think it would be great to be able to define custom transformations
which would apply to both sides of the lookup. This would be particularly
helpful when you want to perform some lookup insensitive to some SQL
transformation (unaccent or other).
