I came from the C/C++ world, recently I play with a haskell editor named yi-editor, I find haskell build phase is very slow:

  1.Compile one .hs file is slow

  2. When change a little, it will recompile many many files

Compare to c, compile a c source file seems much quick then compile a haskell source file. And if i change a .c file, it only recompile the file i changed, and relink, it's awesome. How can i make my build phase more quick?

Thanks!
