@majosm asked in inducer/pytato#548 (comment)
Can we make this return an instance of a new
DataWrappertype that can__hash__by data instead ofid? That would remove the need for data wrapper deduplication, if I understand the intended use of these mappers correctly.

Not sure; in that case, we probably should probably also override the EqualityComparer, otherwise we would get a lot of hash collisions when caching.
