Data.NullPointer

Tired of using Maybe? Wrapping values in Just makes you sick? Missing your NullPointerExceptions? Add null value to any data type using Data.NullPointer!

Example

importPreludehiding (null)
importSystem.Environment (getArgs)
importData.NullPointergetFirstArg:: [String] ->String
getFirstArg (x:_) = x
getFirstArg []=null
main =do
arg <- getFirstArg <$> getArgs
if isNull arg
thenputStrLn"No argument passed"elseputStrLn arg

What if I forget to check if a value is null?

You'll get a NullPointerException, just like in Java! Brillant!
