Hilbert not implemented on Rays

[ettersi]

I'm trying to compute the equilibrium measure of a positive charge supported on [1,2] and a negative charge on (-∞,0]. I believe the following code should work, but it doesn't.

@dlfivefifty mentioned this should be easy to fix. In roughly how long could I expect this to be fixed? In order to be useful to me, it would have to happen within this week.

julia> D = Ray{true}(0), Interval(1,2);
       S = JacobiWeight(-0.5,0.5, Jacobi(-0.5,0.5,D[1])) ∪ JacobiWeight(-0.5,-0.5, Chebyshev(D[2]))
       μ = [
           DefiniteIntegral(component(S,1)); 
           DefiniteIntegral(component(S,2)); 
           real(Hilbert(S))
       ] \ [1;-1;0]

Cauchy/Hilbert transforms have simple maps under Mobius transformations, so supporting this will be almost identical to
