Julia crashes after importing Color after using a @devectorize macro with a colon.

[KristofferC]

I had an issue posted on my package repo about a problem with importing Color after importing my package here: https://github.com/KristofferC/KDTrees.jl/issues/12. I reduced it down to this minimal working example which seems to show that there is a problem with how the Color and Devectorize packages work together.

julia> using Devectorize

julia> @devec best_dists[:] = sqrt(best_dists)
ERROR: best_dists not defined
 in anonymous at no file

julia> using Color # Boom

This works fine:
