How exactly do I require threading macros in Racket?
Following this guide: https://docs.racket-lang.org/threading/index.html I try (require threading) but I get this error:
standard-module-name-resolver: collection not found
for module path: threading
collection: "threading"
in collection directories:
/Users/user/Library/Racket/6.9/collects
/Applications/Racket v6.9/collects
... [163 additional linked and package directories] in: threading
