spurious names

hello,

i run into the following problem:

class C t where
   elem :: t

-- default_elem = 3

-- when default_elem is not used
-- INTERNAL ERROR: pmcTerm

-- instance C Int where
--   elem = default_elem

-- when default_elem is used
-- INTERNAL ERROR: typeAp1

-- when default_elem is not defined (at command prompt)
-- :i default_elem
-- default_elem :: <unknown type>


it looks like hugs introduces new (valid) names into the program.
would it be possible to hide this from the user?

thanks
iavor
