I like this idea.
How about some more syntactic sugar?
{-# LANGUAGE ImportSugar #-}
import [Data.[Text, Foldable q-as F, Vector (Vector), Vector q-as V hiding
(Vector)], Control.Concurrent, Data.List q (sum)]
- tree structure, one import per leaf
- prefix qualified -> postfix q
- qualified/as
this is a funny trick, and it looks saner than the more general $ *
combinators.
i see many situations where i could use that to lift my own combinators,
or to replace the backticks (``) to lift the infix function.
thx

very insightful, thx Jerzy.
imho, this is a good reason not to use already known words like
lift,return,inject,pure etc. while still using the word Monad. (this is
something that bothered me for years.)
no one -of those who say no one- does understand Monads because it does not
explain itself
i get this spam whenever anyone sends a mail to @eukor.com and this list at the
same time.
i think that this kind of spam-bot sends to all recipients, not only to the
person who sent it; but sends only if it sees @eukor.com in the TO: or CC:
field.
so, if anyone knows a similar

Those are damn strange reasons to restrict oneself to 80 chars, iMho.
I tend to look at ONE file at a time, on one fullscreen widescreen.
100 chars per line is more or less normal; I have my vertical line limit marker
set to 100, but only for layout-zen. My lines have sometimes 200 chars
Hi Thomas,
this should be on the haskell-cafe or haskell-beginners mailing list.
Haskell@... is mainly for announcements.
You have:
f :: Monad m =
a - m b
Data.Traversable.mapM :: (Monad m, Traversable t) =
(a - m b) - t a - m (t b)
So, if you define g with
g
you are right, that pice of code is ugly. i would write sth simmilar
(Int32-[Word8]) like you did, iff it should be able to cross-compile or do not
need to be fast or should not need TH.
well, i think, in the case of joel's project the last sentence means ..., iff
true or true or undefined.
is
well, fastest conversion to compute could be an assembler-command, but if we
don't use that, it could be converted via Foreign.Storable and sth like the
following: (i did not test it, and i hope, TH works like this...)
data (Integral a) = BigEndian a = BigEndian a deriving (Eq,Ord,Enum,...)
be
for just making IO and a little bit-conversion, i would use c++ or even c. for
such a problem you have to be near the machine, not necessarily near
mathematical abstraction.
there exist assembler-commands to flip endians of register-values, so i would
just search in /usr/include/*/* for a
nice project. (except that winonly-closedsource-thing. my condolence.)
on which platform are you programming? mac? linux-ppc?
i see that you understood most of that code.
big-endian-test: the number 1234 has two ends (like a sausage), the end with
the 1 is the big end (1000), the 4 is the
maybe, i completely missunderstand you. please, could you program your example
in another language than haskell, one you know better?
i'm not sure -- did you try to define variables instead of types?
data Employee = Emp
data Department = Dept
translated to c++ this means sth like
typedef void
map (foo 5) my_list_of_lists_of_doubles
1. map (flip foo 5) my_list_of_lists_of_doubles
2. map (`foo` 5) my_list_of_lists_of_doubles
3. map (\x-foo x 5) my_list_of_lists_of_doubles
4. [foo x 5 | x - my_list_of_lists_of_doubles]
well, i've followed this discussion a while, but i did not see
google: What the hell are Monads
http://www.abercrombiegroup.co.uk/~noel/research/monads.html
IO in haskell is really easy, iff you understand the sense of monads.
to understand sth. like IO Bool you have to remember that i.e. an array is no
defined data type without the definition of its
on.

looks like a genetic algorithm, i've programmed years ago. :)
i need the sourcecode to solve the problem.
it seems that you zip the two strings together:
unzip $ zip abcde 123
-
unzip [('a','1'),('b','2'),('c','3')]
-
(abc,123)
i've no idea why you got saaturn.

It would be nice to be able to overload class-functions like
classes:
instance (+), (-) - Vector where
(+) v1 v2 = ...
(-) v1 v2 = ...
instead of overloading parts of a class... (because of
runtime-errors!)
instance Num Vector where
(+) v1
what do you want to execute if you do not have a
main function?
i.e. this LHS-file:
--rzsjztj ästrhü
module Snoop where
rjstöh gitsh
schnuck :: IO () schnuck = putStr
"schnuck"
sdfthsrthk
gumble :: IO () gumble
