Weird limitations with Expressions

I have tried myself at using Expressions for quickly throwing together some simple functionality right in the editor, without opening the script editor. I just export an array of Strings. But apparently assignment is not allowed in these expressions! Method calls are fine, but assignment doesn't seem to be okay. Here is what this looks like:

The method calls actually work perfectly fine here, but the assignments (with = in the line) do not seem to work. It seems to complain about there missing another = even though it is already there. Does someone have an idea on why this might happen?

I am not familiar with the feature you're using, but an "expression" is just some code that evaluates to a value; in other words, it's the right side of the equals sign.
- Oh yeah, that makes sense. In the documentation the only actual example they give for expressions is a math equasion, so I guess the code-executing features just came naturally... So I guess I will have to write methods for everything now...
  
  Or maybe try to have your methods as a left side.. example: Expression: print(<your assignment>)
Most variables have setters for situations like this. Rather than using get_tree().paused = false, try get_tree.set_pause(false). There's also Input.set_mouse_mode(), you'll see them under the variable names in the docs.
