Anything declared with `defvar' is a variable which will be
dynamically-bound by `let'. If you don't let-bind it, then it's just
a plain old global variable (tho potentially buffer-local, of course).
Yes, dynamic-scoping is very common, and will stay common in
lexical-binding code, but I don't think that should be a problem.
