we get the following message when we load into ghci (6.8.2)
Var/Type length mismatch:

is this a bug? if not, what is this message telling us ?
I can't reproduce it with 6.10.1, so I presume it is a now-fixed 6.

Cheers,
consider the following types (from the paper:
"Stream Fusion From Lists to Streams to Nothing at All")
data Stream a = forall s. Stream ( s ->(Step a s)) s
data Step a s =
Done
| Yield a s
| Skip s
an instance of this data type is:
stream0 :: Stream ()
stream0 = Stream (\ s -> Yield
