[nem-en] Declaring Properties in the constructor - ala Boo

[Mark Haniford]

That's not the same thing.  In Boo, you can have a default constructor (or
one with no arguments), and then supply as many property values as you see
fit at instantiation.  Your example just shows named parameters, which is
nice, but you still have to define your constructor as normal, and at
instantiation you still have to supply the same number of arguments.  Notice
in my example, that I only defined the constructor with an int being passed
in, and the string is an optional property value.  See the link I posted
earlier for the Boo example.
