Re: [julia-users] convincing Julia that a function call (via a variable) has a stable return type

[Jeff Bezanson]

That's surprising; I get the same speedup in 0.3 with

function test2()
    f = CFunction{Float64,Float64}(foo)
    for i=1:100000000
        r = call(f, 1.0)
        goo(r)
    end
end
