Right, but the documentation you're using is from Hugs. Use the GHC library documentation instead. -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH

Why no "join" function?

Because we removed it from the bytestring package in version 0.9. It had been deprecated for some time in favour of intercalate.

So that's why the version of hugs you're using has it still but the more recent version of ghci you're using does not.
