[julia-users] The unique function and iterables of custom composite types

[Marc Gallant]

The unique function doesn't appear to work using iterables of custom 
composite types, e.g.,

julia> type Foo
       x::Int
       end

julia> import Base: ==

julia> ==(f1::Foo, f2::Foo) = f1.x == f2.x
== (generic function with 85 methods)

julia> unique(foos)
2-element Array{Foo,1}:
 Foo(4)
 Foo(4)

julia> unique(foos)[1] == unique(foos)[2]
true


Is this the intended behaviour?
