I am wondering about the visibility of definitions in the Hugs
Prelude. More specifically, when I ask for info about the Eq class, I
see a lot of instances, including:
instance Eq Key
On the other hand, Key is not in scope:
Hugs> :info Key
Unknown reference `Key'
I imagine this has to do with importing/exporting, or maybe some
modern Hugs empty-Prelude funkiness. Or perhaps it is because Key is
a "non-standard export" (but that is just a comment in the Prelude).
In any case, is it intended that ":info" will tell me about things
that I (and it) can't otherwise see?
Please forgive my naivete re module rules in advance ... .
