yes.

On Smalltalk and class methods:

in Smalltak class methods are methods on the meta class, a meta class is
automatically created behind the scene for each class, and class methods are
only accessible through the class as in:

MyClass metamethod...

myinst class metamethod...

but:

myinst metamethod

would cause a message not understood exception.
