How Does Godot v4.5.1 Handle A Misspelled Global Variable?

Godot Version

v4.5.1.stable.official [f62fdbde1] Linux

Question

How does Godot v4.5.1 handle a misspelled global variable?
Not the declaration of the global variable but rather when it is used.
I think I saw one in “T-Story 110%” today but I can’t remember where.
There is not an error produced in the editor console output either?
Would be great if this could be added? Typo’s in source code…

It will fail to compile with an error message along the lines of “<typo> not defined”

Ok, that makes me feel better, thank you!
No errors on running from editor so all should be OK.
