...yet it works on one of the for-loop values in isolation, and in map.

julia> X=[[true,false],[false,true]]
2-element Array{Array{Bool,1},1}:
 Bool[true, false]
 Bool[false, true]

julia> [.!x for x in X]
ERROR: UndefVarError: .! not defined

julia> .!X[1]
2-element BitArray{1}:
 false
  true

julia> map(x->.!x, X)
2-element Array{BitArray{1},1}:
 Bool[false, true]
 Bool[true, false]

this is on both 0.6 and 0.7-dev.
