there is, as far as I remember, a default setup for code generation for
type 'a word, but no mapping to any target-language-specific types.  If
this is desired, it would be required to wrap up type expressions like
e.g. "64 word" into a dedicated type, say, "word64", to have dedicated
types for all the different 'a word instances.  This wrapping is simple
but cumbersome to do.

Hope this helps,
