Dear Haskell folk,
PLEASE READ THIS IF YOU USE THE Glasgow Haskell Compiler (GHC).
I virtually never send messages to overlapping sets of lists, but I'm
doing so this time, because I'd really like to get to everyone who uses
GHC.
Here at GHC HQ, we are often asked how many people use GHC, and w
You are correct. Moand.Cont yield even runs without -O optimizing,
just slower:
Monad.Writer counts 10^9 zeros in 99 seconds (user time)
Monad.Cont counts 10^8 zero in 35 seconds user time.
So the writer is 3.5 times faster without '-O'
With -O
Monad.Writer counts 10^9 zeros in 105 seconds

Anyone have an idea why ghci can't garbage collect it?
Is this an actual bug or an innate quirk of the REPL ?
GHCi does not "compile" with optimizations, without -O the strictness

isn't run.
The optimizer
Hello all,
I am a new learner, and i am trying to write a function to calculate
factorial of a natural number:
(I use ghc 6.4, window xp)
fac :: Int -> Int
fac n
| n == 0 = 1
| n > 0 = fac (n-1) * n
| otherwise = 0
this works when n < 14 and result is 1278945280, when n > 14 the answer
is not right

Hi,
the difference is that you restrict your function to Int,
whereas the default type is Integer. See:
http://www.haskell.org/onlinereport/decls.html#sect4.3.4
and
http://www.haskell.org/onlinereport/basic.html#sect6.4
hth,
claus
btw, you can ask ghci to give you the type of each
expression
