Auto-fix/refactoring idea: use safe deference and coalesce instead of contains and ternary operator

I have a long list of global variable overrides in every Module ... so much easier to read...

Other comments:

Great idea! I think these types of codefix suggestions are super important for teaching people about new language features.

I make soft growling noise in the back on my throat every time there is a static analysis warning without a auto-fix.....
