Hi,
I am trying to write some Haskell application using COM.
One application is controling the LEGO robot.
The robot works fine when I code my program using VB.
However, when I use Haskell, there is an error: "invoke fail", "invalid
number of parameters".
Because my Haskell program can be comp
Chapter "IO" of the Haskell 98 Library Report contains this example:
import IO
import System
main = do
[f1,f2] <- getArgs
h1 <- openFile f1 ReadMode
h2 <- openFile f2 WriteMode
copyFile h1 h2
hClose h1
hClose h2
Hi,
Is there a way to let hugs show the intermediate
expressions in a reduction sequence?
There's a module that comes with hugs called "EvalRed.hs"
which has functions that do something like this, but it only works for
expressions of the type "Term", where
Term = Square Term | Plus Term

Is this really due to color differences of the order of 10^-17, or
rather due to different libc-inherited random n

Ahhh! Looks like it covers the case of deriving for newtypes!
Does every currently derivable class fit into this?
I wonder if it's able to derive Dynamic, which
There was earlier some discussion on the Basic algebra proposal
(basAlgPropos), in particular, about the Sample argument approach
(SA).
This SA is somehow opposed by the Haskell community.
On the other hand, it may occur that the dependent types, Cayenne
provide some alternative approach
