That may be reasonable. I think it likely makes more sense than making the type of shift depend on the type of number, anyway. On Jul 13, 2014 3:43 PM, "Henning Thielemann" < schlepptop@henning-thielemann.de> wrote:

3. I would like to add explicit arithmetic and logical shifts to
Data.Bits. When fiddling bits, it's often easier to think about that distinction explicitly, rather than in terms of whether the type is signed or unsigned, and more convenient to have an explicit operation rather than casting around.
What kind of data do you have in mind, where both signed and unsigned shifts make sense?
So far, I'd say, that calling "asr" on Word and "lsr" on Int should be a type error.
