I currently have functions like

```julia
function AnalyticalExpectation(distribution::Normal, g::Function)  
    if(g==log)
        return ...
    else
        println("Not yet implemented")
    end
end

```

Is there a way to make this

```julia
function AnalyticalExpectation(distribution::Normal, g::IsLog)  
        return ...
end

```

instead?

You could do `f(distribution::Normal, g::typof(log))`
