How to deal with exceptions? (and other beginner notes)
Specifically the situation that I ran into was when a line_edit node is empty. I thought I found the answer:

` proc on_inbox_text_changed(intext:string) {.gdExport, raises:[IndexDefect, Exception].} =`

But this does not seem to change anything (exception still occurs from this signal, all code still doesn't run when this occurs).

All newest stable stuff. (Godot 3.4, Nim 1.6.0, Godot-Nim 0.8.5)

-----------------------

I'm a beginner with both Nim and Godot, would be nice if there was more info on things to keep in mind when starting. For instance [I made a thread on r/nim](https://www.reddit.com/r/nim/comments/qodqyc/godot_for_beginner_projects_alternatives/) on my thoughts (of which the above issue is one). One of the things was that I couldn't add to certain values (for instance `position.x` as gdscript allows) but I did figure out a way to at least get something working.

Also search on the io page seems to be broken.
