Hi all,
I need to use duplicate instances. I read in the documentation on GHC
6.4, that overlapping class instances checks are lazy instead of gready
in 6.4. However, my code still gives duplicate instance errors when
compiling in GHC 6.4.
Is the duplicate instance check still gready? Is there
Hallo!
The ghc user guide says that there are 4 states a heap object may be in.
Unfortunately in my program there are 5 states (inherent_use, use, drag,
lag, void) with inherent_use being the biggest part (many MBs) and the one
not mentioned in the users guide.
My question is what does it mean?

There was a typo in the code I posted:

Just thought I ought to point out that all this is only necessary if the
datasources may return different types... If you want them to return the
same type you only need:
instance (Datasource l k v,Datasource r k v) = Datasource (JoinedDS l
r) k v ...
As both datasources have the same key and
