[Haskell-cafe] Do expression definition

Hello. http://www.haskell.org/onlinereport/exps.html#sect3.14 a obscure (to me) note which says As indicated by the translation of do, variables bound by let have fully polymorphic types while those defined by - are lambda bound and are thus monomorphic. What actually does it mean? And,

[Haskell-cafe] bug in Network.Browser

Hello. Yesterday I hit a bug in Network.Browser: connection in the connection pool is not reused if you are connecting to a destination with qualified port (not 80 for HTTP or 80 but explicitly provided like http://www.google.com:80). The reason for the failure is quite trivial, but I had not

[Haskell-cafe] Typo or on purpose? http://haskell.org/ghc/docs/6.12.2/html/users_guide/lang-parallel.html

This + 1 in (n1 + n2 + 1) what is it doing there? import Control.Parallel nfib :: Int - Int nfib n | n = 1 = 1 | otherwise = par n1 (pseq n2 (n1 + n2 + 1)) where n1 = nfib (n-1) n2 = nfib (n-2) BTW, same code can be found in Seq no more:

[Haskell-cafe] Odd parallel haskell observations

Hello. I am exploring haskell features for parallel and cocurrent programming and see something difficult to explain. In brief - asking RTS to use more threads results in awfull drop of performance. And according to 'top' test programm consumes up to N CPUs power. Am I doing something wrong? I

So updated to HaXml 1.20, haxr 3000.7 Simple calls (which deal with simple data types as integer or regular string) still work. Calls which successfully returned some binary data before do not do so anymore. The error is: Prelude.chr: bad argument: 1177427 Calls which complained about 'white'

Hello. I decided to run a couple of test XML-RPC applications using haxr. Everything worked fine while responces from my (actually, other people's) server were something relatively small (a number, a line), but with larger responces (starting around couple of kilobytes) my applications began to
