function check_generic_array(body)

Current one makes a trade-off for the performance of expr template patterns and normal array patterns.

Following one could be faster when it comes to normal array destructing.

 function check_generic_array(body)
            @format [Array, SubArray, UnitRange, Tuple, Int] quote

                @inline __L__ function NAME(TARGET :: Array{T, 1}) where {T}
                    body
                end

              @inline __L__ function NAME(TARGET :: SubArray{T, 1, Array{T, 1}, Tuple{UnitRange{Int}}, true}) where {T}
                    body
                end

                @inline __L__ function NAME(_)
                    failed
                end

                NAME(tag)

            end
end
