$CODE
/ Design Influences: $CODE, as a sequence of $OP items, draws inspiration from Lisp's code-as-data paradigm, supporting composable and introspectable execution trees. This approach is chosen to make Grapa accessible and powerful for a broad audience, with a special focus on usability for Python programmers and educators. / A sequence of $OP items to be processed in sequence. Normally you would use $CODE directly. It is typically embedded in an $OP type. The planner typically wraps the result in an $OP along with parameter handling for the function - but this could change at some point where it could be either $OP or $CODE.
Example: Assigns 2 to a, than evaluates a3, the result is 6 Commands | Results ------------ | ------------- f=@[1,2];f(); | 2 f=op(){a=2;a3;};f; | @<[op,@[@
