the obvious reply is: If you want to talk to the class you need a
message implemented as a class side method. Examples:
a := Float pi
asks the class Float to return an instance of Float with the value of
pi. So you'll find the method pi implemented on the class side of
then a:= a + 3.0 talks to an instance of Float so you'll find +
implemented on the instance side of Float (or on of its superclasses).
