No, whether it's implemented in C or in Lisp is irrelevant. As soon as
you put a symbol into a `quote`, it can't be a reference to a lexical
variable any more because the compiler will treat it as data and data
cannot refer to lexical variables, only to other data.
Dynamically scoped variables are data, on the other hand (they're just
a particular field of a symbol object, which is a kind of "struct").
