Forms like `fluid-let' don't actually make dynamic decisions about *scope* -- they just mutate an existing, statically-scoped variable. We're really just talking about dynamic decisions about *where a variable is bound*, not *what the current value of its binding is*. That said, I happen to know Mark thinks fluids are a bad idea too. :)
