[racket-users] PSA: alexis/collection is dead, long live data/collection

Earlier this year, Jay suggested I move alexis/collection to data/collection and claim that namespace. In the past week, I’ve finally done so. Instead of using the alexis-collections package, just use the collections package. Otherwise, everything still works identically. The
