Hi all,
I was surprised to find out that the following piece of code:
length [1..] > 10
isnt lazily evaluated! I wouldnt expect this to be a bug, but in this case, shouldnt the computation end when the length function evaluation goes something like:
10 + length [11..]
?
In an ideal world, yes.
In this world, use "length (take 11 [1..]) > 10"...
not (null (drop 10 [1..])) is surely faster (not tested...) jcc
