[julia-users] UnionType -> tuple of DataType(s)

[Tony Fong]

Hello, new user and subscriber here. Is there a way to decompose a 
UnionType back into its constituent type(s)?

I tried names():

> dt = Union(Int,Float64)
> names(dt)
1-element Array{Symbol,1}:
 :types

convert() seems to hit dead-ends.

Help appreciated.

Tony
