import

[syntax] import name

ChezScheme, STk, STklos, Gauche: Imports bindings exported from module name.

Chez's import affects local bindings, while STklos and Guile's affect only the global bindings.

  Chez:
  (module m (y) (define y 'm-y))
  (let ((x 'local-x) (y 'local-y))
    (import m)
    (list x y)) ==> (local-x m-y)

  Gauche:
  (define-module m (export y) (define y 'm-y))
  (let ((x 'local-x) (y 'local-y))
    (import m)
    (list x y)) ==> (local-x local-y)

In other words, Chez's import works as if the bindings that are exported from the module are inserted where the import form appears.

[module clause] import module

Chicken: Can only appear in the module clause of define-module. Imports symbol from module. import can be a symbol or (symbol rename). You can selectively import symbols, optionally renaming, or give no imports to import all exported symbols. The second form is the same as (import (module)).
