Hi

I have wondered why the designers of Dylan choosed to not include some
kind of null or nil constant. Dylan programs seems to use either a type
union including the singelton #f as representing no object or making two
subclasses one which defines the object and one which defines the "no
object".

Thankyou in advance for any answers
