I agree, the interactive cross-referencing features of Smalltalk
environments are wonderful, much faster and better than I have seen
for other languages (Microsoft C++ is pretty good, except for being
slow). They do have one weakness that is related to dynamic typing: if
two or more semanticly unrelated methods have the same name, you have
to manually sort out the senders of the one you care about from
senders of the other methods. Such name collisions get harder to avoid
as the program size and project duration increase. It seems to me that
either (optional) static type declarations, or namespace management
features, or both, would help here.
Another reason to think that some kind of declarative type feature
could be useful in Smalltalk is that good Smalltalk programmers
typically use naming conventions and sometimes even comments to
indicate what kinds of values are expected to be bound to each
variable. The idea of formalizing this just enough so that the
information is available to automated tools is appealing to me.
