Some of the verbosity of units can be reduced using the "inference" features that Racket's unit system provides. Here's one way to do this: ;; define a signature that contains info about your runtime data (define-signature runtime-data^ (runtime-value)) ;; define a unit that encapsulates the initialization of data you need at runtime (define-unit runtime-data@ (import) (export runtime-data^) (define runtime-value ...)) ;; Implement the rest of your program in a unit which imports the runtime-data^ signature (define-unit use-runtime-data@ (import runtime-data^) (export) ;; your main program code goes here ... ) ;; link together the units to run your program (invoke-unit/infer (link runtime-data@ use-runtime-data@)) There is still some syntactic overhead, but using unit inference does alleviate many of the confusing parts of manually linking and invoking units.
