Whoops! Here is the updated code:
julia> type Foo
x::Int
end
julia> import Base: ==
julia> ==(f1::Foo, f2::Foo) = f1.x == f2.x
== (generic function with 85 methods)
julia> foos = [Foo(4), Foo(4)]
2-element Array{Foo,1}:
Foo(4)
Foo(4)
julia> unique(foos)
2-element Array{Foo,1}:
Foo(4)
Foo(4)
julia> unique(foos)[1] == unique(foos)[2]
true
