You are probably right. Anyway, there's more to it than that.
For example, there is also the plan to have explicit:

     val(lambda-expression)

be used as the phoenix equivalent of

     unlambda(lambda-expression)

Behind the scenes, there's some work being done to make this happen.
I don't think I've committed such code. I'm not quite sure about
it.
