Autocomplete suggestion order does not take scope into account

[chinedufn]

I couldn't find a related issue for this, hopefully I'm not opening a dupe.

In the below screenshot I would expect the model_matrix to be suggested before model_matrices when I'm auto-completing inside of the for loop.

And in general, when I'm inside of a loop / closure / etc I'd expect the arguments to be considered more relevant than anything outside of the loop / closure / etc scope.

On the nice side though after my first completion it starts highlighting model_matrix (even though it's still lower in the list) so this only happens once per variable (which can be inconvenient but not the end of the world).

Thanks !!

We don't have the general completion sorting infra in place yet.
