How did you understand it then?
There's a bit different than what I originally wrote.
The first thought was to map-assign the data:
And now it's more general:
result = mapping(a, b, binary_op_on_data)
returns a view which is also associative
FWIW, "mapping/left_mapping/full_mapping" are analog to "inner
join/left join/full join" in relational DB.
Could you please provide some rough text about

I intend to do it for mapping between different pixel formats.
eval(left_mapping(view(dst), src, alpha_blend));
