Haskell does take a long time to compile from scratch, but once you compile once, it is much much faster. The annoying bit comes when you end up changing something which means a lot of other things end up needing to be recompiled, but there are ways to mitigate that, and overall I think haskell is very worth the tradeoff. I often think about "what would replace haskell?" though and ponder it, and I do think that most likely one feature will be a faster compiler (though I don't really know how possible that is to maintain feature parity).
