... Whether 'tis nobler in the mind to suffer, The slings and bugs of outrageous compilers, ... The current GHC-4.00 from the CVS repository highlights a bug in the Haskell Library Report: There is confusion between isAlphanum and isAlphaNum in the report and in the compiler. Hmmm, IMHO that?s a little bit *too* obedient to the report... ;-) Although isAlphaNum looks nicer, previous GHCs, Hugs, NHC, and HBC all use isAlphanum, so this should be the right choice. Another minor thing: Compiling the Word module needs more than the given 12MB heap, e.g. 16MB did it for me. Cheers, Sven P.S.: We digged up a G3 PowerPC machine running Linux here, so releasing 4.01 in .hc-style, too, would be nice.
