I understand why Plot[Random[],{x,0,1}] and Plot[Evaluate@Random[],{x,0,1}] result in clearly different plots. And these two do illustrate the arguements to plot are evaluated differently than arguments to other functions.

The only real difference I see between a simple expression and a complicated expression is when the simple expression consists of a fundamental function (one not written in Mathematica code) there really isn't anything for Compiled to do. Consequently, I was pointing out I would expect Plot[Random[],{x,0,1},Compiled->True] to result in the same plot as Plot[Random[],{x,0,1},Compiled->False], i.e., Compiled should not make a difference. So, I do not understand what relationship these examples have to do with the point you are making. In fact, I don't really see a problem.
