apparently a kotlin script cannot implement abstract function the script definition.. or at least ide things its a conflicting overload

Yep, it is not possible at the moment, and there is no easy solution for it now. Feel free to add an issue to the YT though.

Thank you for reporting. As I said, it is not something easily fixable, but it is good to have it reported anyway.

it would be such a powerful feature to have function that need to be implemented scripts can then be evaluated and functions can be executed later or multiple times without re-evaluation also it gives the user a good idea of what they should write in the script
