Hi All,
I'm pleased to announce the initial alpha release
of the Disciplined Disciple Compiler (DDC).
Disciple is an explicitly lazy dialect of Haskell which includes:
- first class destructive update of arbitrary data.
- computational effects without the need for state monads.
- type directed fi

L.S.,
When playing with exceptions, I noticed the following strangeness:
*Main> 1 / 0
Infinity
*Main> 1 `div` 0
*** Exception: divide by zero
This is in GHCi 6.8.2; WinHugs Sep 2006 gives:

1.#INF
Main> 1 `div` 0
Program error: divide by zero

Let me summarize :-)
The current design for type functions with result kinds other than *
(e.g. * -> *) has not gotten very far yet. We are currently stabilizing
the ordinary * type functions, and writing the story up. When that's done
we can properly focus on this issue and consider different

Oops, two mistakes here:
1) StringE should be StringL
2) splices need to be in the Q monad.
To fix (2), you can either add a "return" here, or, there are

First off, the first code isn't doing exactly what you think; gen1 3,
for example, generates the parse tree:
"<<" ++ show 3 ++ ">>"
You can improve this in the following way:
gen1 i = let x = "<<" ++ show i ++ ">>" in [| x |]
which generates (for gen1 3, again)
['<', '<', '3', '>', '>']
