105 An alternative is to analyze T in Grid{T,D} to find the answer. (See combined_coordinate_vector_type in tensor_grid.jl) 106 An alternative is to analyze T in Grid{T,D} to find the answer. (See combined_coordinate_vector_type in tensor_grid.jl)

108 ## Lazy version of map for our needs?
109 Could be used to
110 * evaulate functions on grids
111 * pick out components of grid functions
112 * More?

114 Maybe this:
115 ```julia
116 struct LazyMappedArray <: LazyArray
117 f::F
118 v::AT
