Searching google for "collapsible contract" should point to these pages, at least: https://docs.racket-lang.org/reference/collapsible.html https://users.cs.northwestern.edu/~dmf082/papers/collapsible.pdf In short, racket/contract has two flavors for some contracts: "normal" and "collapsible". Those log messages appear when the library tries to use "collapsible" but has to fall back. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
