> With dynamic binding, the last call ((mymap [f _] '(1 2 3 4 5))) would instead be an infinite loop

No, the parameter names in a function are in the lexical scope so they can't be modified by a dynamic scope.

That is, f is not a free variable in mymap. It get's lexically bound to the value of the first argument.

Fair enough. That's my fault: I wasn't entirely clear on dynamic binding. The rest of my objections do still stand, however :)
