Integer (gmp) performance regression?
For a simple program that uses Integer, but actual data would fit in an Int, ghc-8.0.2 seems to have more runtime overhead than ghc-6.12.3 had: http://www.imn.htwk-leipzig.de/\~waldmann/etc/mob/
I am not really sure what to make of it - an answer could be: "if you know that your Integer fits in an Int, then just use Int".
