Why do you single out generics? There is no type annotation support in 
jython _anywhere_, it is the very reason I prefer jython over java in 
most cases.

So why should anybody expect

foo = "bar"
foo = 100

to work, while

map.put("foo", 100)
map.put(100, "foo")

expect to puke with type errors?

So I'd say no, there is no need to especially document that.
