Am a bit stuck here,... please, what is wrong with this?
checkNode :: String -> [String] -> Bool
checkNode s nodes =
[s == node | node <- nodes ]
src/me.hs:3:4:
Couldn't match expected type `Bool' with actual type `[t0]'
[1 of 1] Compiling Main ( src/me.hs, interpreted )
In the expression: [s == node | node <- nodes]
Failed, modules loaded: none.
In an equation for `checkNode':
checkNode s nodes = [s == node | node <- nodes]
thanks,
Miro
