I don't understand what part of this doesn't qualify as a "reusable module" to you.
- How do you search for a function other than by description or name. Assuming the developer classified properly and you even happen to use the same domain language as the writer.
- When multiple modules are returned, similar packages, how do you compare and select efficiently without wasting hours reading the code, evaluating it, checking if it is still maintained and hoping there are no hidden bugs etc.
It is easy to share code. Package manager even facilitate updating code. But it is still a nightmare to find/discover code and reuse it
It's like building a lego set. You know the building block you want but if you have to spend hours looking for it, you give up.
I believe competent developers write shitty code not because they are lazy or inexperienced but because the cost of writing great code is very high.
You were asking for modules and now you're down to the function level. That's a much easier problem to solve. Hoogle, Javadoc, documentation and good index engines solve this problem easily.
Note that type only is pretty ambiguous and most of the time useless without additional metadata. Types tell you what, they don't tell you why or how.

At some point, the human brain has to step in and make a call. You can't expect an automated tool to dictate to you the code you need to write.
