[Nix-dev] Would having a toBool function be nice or insane ?

[Marc Weber]

What do you think about introducing a 

lib.toBool = value : ! (value == false  || value == null || value == "")

function?

I'm not sure about the last  value == ""

It could be used in

mkDerivationOrBootScript = {
        enableFeature = lib.toBool config.[..]
        indstead of
        enableFeature = if config.[..] then true else false
}
