Hello,
The context in your example serves an important purpose: it records the fact
that the behavior of the function may differ depending on which type it is
instantiated with. This is quite different from ordinary polymorphic
functions,
Hi Miro!
I have no useful information for you. Few weeks ago I also checked for
any AI (machine learning first of all) related packages exist and
found nothing satisfactory except for some quite small packages
implementing a single algorithm (like NN-back-propagation). So there
is a lot to do :)
Roman,
I think this question is for Richard. I haven't had a chance to play
with these methods. I will try to do that today.

Isaac,
I see your point. Probably I shouldn't have made that assertion given my
limited understanding of the benchmarks. I want to thank you for your
kind and gentle way of pointing this out to me. I feel very welcomed and
encourage.
I still plan to work on the performance paper with the
Thanks David.
I'm glad to see it was discussed in the wiki. (Btw, my 2 cents is that I
like the comment pragmas more than new keywords.)
The issue that I think doesn't make it into the wiki is of splitting, not
modules, but* type-classes*. That's where I think it becomes a more serious
issue.
I have been playing around with the latest cabal-install (0.14.0) and it is
working really nicely. Having unpacked a cabal bundle you can now type
'cabal install' inside the root and it will work everything out as if you
had asked to install directly from the repo -- very nice.
I have also
Hi,
It is quite likely that the error that you are getting with approach 2 is
because when you are constructing the `Combinator` value, there is not
enough type information to figure out how to solve the constraint (and it
sounds like this happens because there is not enough type information to

Good point, Antoine!
I think that does the trick.

I understand. Thank you. I will be more careful about my wording in the
future. I really do appreciate your taking the time to point this out to
me. I am here to learn and help where I can.

Sure, the proposed syntax wasn't a serious proposal as it has
backwards compatibility issues so
Indeed, cabal-install 0.14.0 has been *excellent* for me so far. Thanks
