 One caveat — you're still in a Pollen markup file, so the return value of whatever function you call has to produce a string or an X-expression, so it can be merged into the document. That's why we have @racket[number->string] wrapping the numerical values. (This is similar to the restriction introduced in the @seclink["Setting_up_a_preprocessor_source_file"]{first tutorial} where functions used in preprocessor files had to produce text.)

 This will produce an error in DrRacket:

 This code would not, however, produce an error if it were being run as a Pollen preprocessor file, because the prepreocessor automatically converts numbers to strings. If you'd like to verify this, change the suffix to @code{.pp} and run the file again.
