Binds each identifier in @racket[id-list] within the
@tech{internal-definition context} represented by @racket[intdef-ctx], where
@racket[intdef-ctx] is the result of
@racket[syntax-local-make-definition-context]. Supply @racket[#f] for
@racket[syntax-local-make-definition-context].
The @tech{lexical information} of each element of @racket[extra-intdef-ctxs]
is also added to each identifier in @racket[id-list] before binding.
Supply @racket[#f] for
@racket[expr] when the identifiers correspond to
@racket[define-values] bindings, and supply a compile-time expression
when the identifiers correspond to @racket[define-syntaxes] bindings;
in the latter case, the number of values produced by the expression should

In the latter case, the number of values produced by the expression should
match the number of identifiers, otherwise the
