[julia-users] `methodswith` on `Union` types

[Ethan Anderes]

I’m not sure if this is a bug or not but methodswith doesn’t seem to work 
on Union types.
I came across this working with a linear fit in the GLM package

using GLM, DataFrames
lmfit = lm(y ~ x, DataFrame(x=[1,2,3], y=[2,3,3]))
methodswith(typeof(lmfit))

Here is a minimal working example

julia> type Type1
           x
       end

julia> type Type2
           x
           y
       end

julia> foo(t::Union(Type1, Type2)) = t.x
foo (generic function with 1 method)

julia> foo(Type1(10))
10

julia> methodswith(Type1)
0-element Array{Method,1}

Here is my version info
