it is intented, because args only introspects the arguments for
procs. For instprocs there is a method "instargs" for the class
object. You will get the expected behavior with:

Foo instproc init {} {
  puts [[self class] info instargs myMethod]
}
Foo ob
--> anArgument

with "[self class] info args" you'll get the args of class-specific
procs
