The thing that made me think was this statement - "Smalltalk doesn't have
static methods, neither does Ruby". The implication being that static
methods are just another Java thing that doesn't apply to dynamic languages.
Am I missing some crucial distinction between static methods and class
methods? I don't know Java well enough to be sure, but the Ruby docs
actually state that they are equivalent. I don't know Ruby, but can anyone
imagine Smalltalk without class methods and variables?
As you said, Ruby does indeed have class methods, and they are the same
thing as static methods - they are not tied to any particular object.
Now, I don't know if there are some subtle differences behind that and
the naming conventions...
As for Smalltalk, I don't know enough about it to say anything useful.
But, I do think static or class methods can provide a useful distinction
between their object counterparts.
