Alias for :quit in GHCi?

Trivial question, just out of curiosity. Why it is not possible to define aliases for :quit in GHCi? Prelude :def ayuda \_ - return :help Prelude :def adios \_ - return :quit Prelude :ayuda ... normal help output... Prelude :adios Prelude -- /L/e/k/t/u

Parallel GHC on Altix?

2006-05-05 Thread Chad Scherrer
Hi, I'd like to get more involved in parallel programming in Haskell, and I have access to an SGI Altix machine (a shared-memory multiprocessor). Can someone tell me, if I download a 64-bit GHC 6.5 snapshot, to what extent will parallelism just work? Specifically, I'm interested in * parallel
