Couldn't match expected type `ChanOpts a'

In the first argument of `oneToOneChannel'', namely `o'
In the second argument of `(<$>)', namely `oneToOneChannel' o'
In the first argument of `(>>=)', namely
`((writer &&& reader) <$> oneToOneChannel' o)'
There's no conflict between the two instances, though. I wonder if
making ConnectableParam depend on "l" and "r" would fix it. I'll look
further into this when I get onto a 6.10.4 machine.
That did indeed turn out to be the fix. That will teach me to release a
package without remembering to test it on GHC 6.10 first. I've uploaded
chp-plus 1.2.0 to Hackage, which should fix this issue (among other
changes). So:
cabal update && cabal install chp-plus
Should work now. Let me know if you have any other troubles.
Thanks,
Neil.
