Hmm, this threatens to get a little philosophical, but that seems to
contradict earlier text in the same node:
Here is how lexical binding works. Each binding construct
defines a “lexical environment”, specifying the symbols that are
bound within the construct and their local values. When the Lisp
evaluator wants the current value of a variable, it looks first in
the lexical environment; if the variable is not specified in
there, it looks in the symbol’s value cell, where the dynamic
value is stored.
