DimensionMismatch after slicing

[jariji]

I was expecting this to work.

julia> let obj  = ['h', 'e', 'l', 'l', 'o']
           @modify(reverse(obj)) do x
               x[1:3]
           end
       
       end

Heh, I guess you are right, it makes sense for set(reverse) to allow changing the array length. PRs to fix bugs / add missing functionality like this are welcome!
