@thevirtuoso1973 is it possible to say something like expected "," or ")" by any chance?

[thevirtuoso1973]

Yes, in a way. I could rewrite the expression parser to be more like parsing binary operators. Then at some point we'll have alt((another_operator, parentheses_close_expression)) and if I cut(alt(...)) then the generated tree should store the alternatives so it would look something like this:

expected ")"
  ┌─ aaa:5:7
  │    
...
or
expected ","
  ┌─ aaa:5:7
  │    
...

Although I probably won't do this now.
