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

Hi Julian,
I'm currently using {{^}} as an operator in the parser, similar to how Calcite
uses it for marking parser positions in their test cases. Since I'm now working
with {{^}} as an operator, how should I go about constructing test cases for
this feature? Any advice on how to approach it would be greatly appreciated.
Thanks in advance!
