i'm not sure whether i'm doing something wrong, or whether this is the
expected behavior, but it might be an error:
julia> const ∪ = union
Warning: imported binding for ∪ overwritten in module Main
union (generic function with 7 methods)
julia> ∪([1 2 3],[3 4 5])
5-element Array{Int64,1}:

5
julia> !(true)
false
julia> const ¬ = !
ERROR: syntax: invalid character "¬"
julia> (¬)(x::Bool) = !x
ERROR: syntax: invalid character "¬"
this is with today's version of julia, on both os x and linux.
