Right, it's sort of hinted at in the elisp manual (11.9.3 Lexical Binding):

    Note that functions like ‘symbol-value’, ‘boundp’, and ‘set’ only
    retrieve or modify a variable’s dynamic binding (i.e., the
    contents of its symbol’s value cell).

I think we should be a little more specific, not
just give examples, something like:

    Note that functions which take a symbol argument (like
    ‘symbol-value’, ‘boundp’, and ‘set’) can only retrieve or modify a
    variable’s dynamic binding (i.e., the contents of its symbol’s
    value cell).
