I guess that you are saying that you need a look up between selectornamespace
because you can have
A>String>>foo
^ 666
A>String>>bar
^ self foo
=> compiled into
A>String>>bar
^ self #A.foo
B import A
B>String>>foo
^ 42
in B
'ababab' foo
-> 42
'ababab' bar
=>compiled in
ababab' #B.bar
should still execute
'ababab' #A.bar since it is not redefined
Yes I agree with you.
