Describe the bug
Autocomplete seems to be working for some items, not for others.

So far I have tested these:

So this is working as expected for something like a function I wrote myself, or myList.forEach(). Not sure why others aren't working.

To Reproduce
Steps to reproduce the behavior:

1. In a function, eg main(), type prin
2. Press Tab to accept 'Print' autocomplete

Expected behavior
The item, eg print() or Text() should be completed with parentheses and arguments if appropriate.
