[Haskell-cafe] A function that makes list of Bool lists from list of Int lists

[Maur Toter]

Hey,

I am new with Haskell so I think this will be a pretty dumb question.
I would like to make a function that makes this:

listbool :: [[Int]] -> [[Bool]]

in this way:
listbool [[1,2],[3,4]] == [[True, True],[False, False]]
listbool [[1],[5,5],[5,4],[2]] == [[True],[False, False],[True, True],
[False]]

So always True from the elements of the first list, False from the elements
of the second one, etc...


Can you help me to do that?
Thanks for your help!
