Potential GSoC proposal: Reduce the speed gap between 'ghc -c' and 'ghc --make'

2012-04-02 Thread Mikhail Glushenkov
Hi all, [Hoping it's not too late.] During my work on parallelising 'ghc --make' [1] I encountered a stumbling block: running 'ghc --make' can be often much faster than using separate compile ('ghc -c') and link stages, which means that any parallel build tool built on top of 'ghc -c' will be

Plus one might argue that using to mean different is a bad choice, as it graphically means strictly inferior or strictly superior which implies comparability, whereas equality and comparison are two different things. (e.g. Eq and Ord are two distinct classes in Haskell). Le 1 avril 2012 23:06,
