Is there an easy way to convert a Boolean to an Integer?

If you want to mix Boolean and Int operation use an implicit as above but without creating a class:

implicit def bool2int(b:Boolean) = if (b) 1 else 0

scala> false:Int
res4: Int = 0

scala> true:Int
res5: Int = 1

scala> val b=true
b: Boolean = true


scala> 2*b+1
res2: Int = 3
