I don't think that this is quite correct... if a name is the name both of
a global variable and of a local variable in an enclosing procedure frame,
then with dynamic scope you get the variable in the enclosing procedure
frame, but with lexical scope you get the global variable.  Neither of
these sets is a subset of the other.

(But I definitely share your affection for dynamic scoping, at least in an
interpreted language in which there's no penalty for it.)
