SAW can't access module parameters

[weaversa]

module SHA::SHA384 = SHA::SHA where

type w = 64
...

SAW can't access w.

sawscript> import "SHA/SHA384.cry" 
sawscript> print {{ `w }}

user error (Cryptol error:
[error] at <stdin>:1:11--1:12 Type not in scope: w)
sawscript> 

Cryptol can:

$ cryptol SHA/SHA384.cry

I was trying to use SAW to verify some code and wanted it to just work with whatever parameterized module I passed in. To do that, SAW needs to be able to access parameters.
