I believe it's partly a problem of lazyness, e.g "I want to type 
less. I want to be proposed `filter` when I CTRL+SPACE after 
`arr.fi` ".

That case can be solved by doing a word split on the current 
document and by adding the results to the "good" completions when 
they are requested. If you have selective imports at the top of 
the module, for filter, map, each etc. then they are proposed as 

The other part of the problem is that completion can be used to 
overcome the lack of knowledge of an API, for example. In this 
case the word split does not help.
