Referenceables

Referenceables.jl provides an interface for readable and writable reference to an element of an array or dictionary. The entry point function is referenceable. Wrapping a container x yields a new view y = referenceable(x) to x where indexing to it yields a reference r = y[i]. This reference can be used to read value = r[] or write r[] = value a value.

Examples

julia> using Referenceables

julia> x = collect(reshape(1:6, (2, 3)))
       y = referenceable(x);

julia> r = y[1, 1] :: Ref
↪1

julia> r[] = 100;

julia> x
2×3 Array{Int64,2}:
 100  3  5
   2  4  6
