I _think_ this may cause problems with some data types (e.g. http://hackage.haskell.org/packages/archive/numbers/2009.8.9/doc/html/Data-N... ) that require the extra laziness (that is, you can do things like ` 3 < genericLength [1..] ' and have it return True).
Does the current version support this? The use of an accumulator (that is presumably returned after consuming the complete input) seems to suggest that your example would diverge anyway (but I did not try).
I was just trying to remember some of the tricks Daniel Peebles (aka {co}pumpkin) used to do in #haskell with Data.List.genericLength. I've never really used ListLike, but was just trying to guess why the default implementation was as it is. -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
