Importing instantiation of the parameterized module doesn't make those values available

//parameterized module
module M where
parameter
  x : [10]
type y = 10

//instantiated module
module N=M where
x = 20

// importing instantiated module
module O where
import N
// but I'm not able to access x value here for some reason

Parameters are kept private. If you want to expose them, you can do something like this:

//parameterized module
module M where
parameter
  _x : [10]
type y = 10
x = _x

//instantiated module
module N=M where
_x = 20

// importing instantiated module
module O where
import N
// Now you can access x

Ah, I didn't know that parameters are private and the above example works. Thanks @weaversa.

I have another question:

module M where
type x = 10

module N where
import M 
type y = 20

module O where
import N
// but I'm not able to access x here but y only
// to access both x and y, I had import both M and N in this module

it seems to me that module importation isn't transitive?

Yes, this helps keep the namespace under control.

I see. Thanks
