[plt-scheme] abstracting over (PLaneT) requires
Here's a simple way:
my-lib.ss:
(require (planet "some-file.ss" ("joe" "a-package.plt" MAJOR (= MINOR))))
(provide (all-from-out (planet "some-file.ss" ("joe" "a-package.plt"
MAJOR (= MINOR)))))
my-old-other-lib.ss:
(require (planet "some-file.ss" ("joe" "a-package.plt" MAJOR (= MINOR))))
my-other-lib.ss:
(require "my-lib.ss")
