I don't really see what you mean in canvasargs. [+] behaves differently when given a bang or a list. Bang outputs the current result again, and a list of two numbers sets two new values to add and outputs the result.
Read it as « a bang or an empty list ».
The bang is cast to an empty-list in a context where a list-method is defined but a bang-method isn't.
