By default, functions are visible outside of their module. You may
restrict the visibility of a function by using the local
keyword:
module Foo local function a = { return 666 } function b = { return a() }
Here, b
is visible while a
can only be invoked from within the Foo
module. Given another module called Bogus
, the following would fail at
runtime:
module Bogus function i_will_crash = { return Foo.a() }
