Hi there, I have 3 questions 1: will ghc for OSX be 64bit by default this time around? 2: is it going to be an issue that for a lot of the new OSX, gcc no longer exist, it's clang-gcc now. 3: any chance we can have uninstall instructions to uninstall previous versions? :) Thanks -- Omnem crede diem tibi diluxisse supremum.
