-

i want have function in foo.internal module used other things in there, should exposed foo module. when reexport function foo use elsewhere linker errors. using stack build code, might issue there, or cabal, not sure.

minimal working example:

module foo.internal secrets = "stuff"  module foo(secrets) import foo.internal (secrets)  module main import foo main = putstrln secrets

when compile stack build get
