 For example:
-@racketblock[(require (multi-in racket list dict))]
+@racketblock[(require (multi-in racket (list dict)))]
 is equivalent to:
 @racketblock[(require racket/list racket/dict)]
 Similarly:
-@racketblock[(require (multi-in "utils" "math.rkt" "matrix.rkt"))]
+@racketblock[(require (multi-in "utils" ("math.rkt" "matrix.rkt")))]
 is equivalent to:

+It is also possible to require to require files with identical names

+@racketblock[(require (multi-in ("math" "matrix") "utils.rkt"))]
+which is equivalent to:
+@racketblock[(require "math/utils.rkt" "matrix/utils.rkt")]
+or even:
+@racketblock[(require (multi-in ("math" "matrix") ("utils.rkt" "helpers.rkt")))]

+Deeper nesting is also possible:
