Feature: Smart autocomplete

[kontomondo]

Would be nice to have something of a "smart autocomplete", invoked by say Ctrl+Shift+Space that would only list the variables/methods that match the expected type.

Say in this case

let processPath (path:String) = ...
let somePath = @"/home/user/data"
let processedPath = processPath [Invoke Smart Autocomplete] 

invoking it would give you values that are of type string.

Another feature it may have is if there's only one match for type in the local scope, it would automatically select that option without a popup.
