@ -544,6 +544,14 @@ resulting syntax object (assuming that the lexical information of
@scheme[stx] includes the binding environment into which the @scheme[stx] includes the binding environment into which the
@scheme[#%require] is lifted). @scheme[#%require] is lifted).
If @racket[raw-require-spec] and @racket[stx] are part of the input to
a transformer, then typically @racket[syntax-local-introduce] should be
applied to each before passing them to
@racket[syntax-local-lift-require], and then
@racket[syntax-local-introduce] should be applied to the result of
@racket[syntax-local-lift-require]. Otherwise, marks added
by the macro expander can prevent access to the new imports.
