Parametric type

Is it possible to write a parametric type with default type?

struct Point{T}
    x::T
    y::T
end

struct Foo
    a::Point{Float64}
    b::Point     # should be the default type: Point{Float64}
    c::Point{Int}
end

No, not as written. b::Point already means something: it means b can have a type which is Point{T} for any T. You could consider doing:

const PointF = Point{Float64}

struct Foo
  b::PointF
  ...

which is only slightly more verbose.
