Named arguments

Scala allows you to specify parameter assignment by name rather than just ordinal position. For example, we can have this code:

def divide(dividend:Int, divisor:Int): Float = 
{ dividend.toFloat / divisor.toFloat }
divide(40, 5)
divide(divisor = 40, dividend = 5)

If we run this in a notebook, we can see the results:

The first call is to divide assigned parameters by position. The second call set them accordingly.
