27 # What does a TensorMapping apply() to?
28 # =====================================
29 # Is it too strict that TensorMappings apply to AbstractArrays? Maybe we don't need
30 # to know the operands size. That could simplify the handeling of the range_size...
31 # It would just fail if apply does something out of bounds..
32 # No i think knowing the size is a requirement. The TensorMapping must be able to do
33 # different things for different indecies based for example on how close to the boundary we are.
