Encapsulation? Seems good to me.

Use a function
julia> module A
a = 1
moda(newa) = global a=newa
end
A
julia> A.a
1
julia> A.moda(2)
2
julia> A.a
2
You can also eval into a module:
julia> eval(A, :(b=2))
2
julia> A.b
2
julia> eval(A, :(f()=22))
f (generic function with 1 method)
julia> A.f()
22
(but use this extremely sparingly!)
