I think it's fair to call the shorter syntax the "default".
You have to say something extra to get short-circuit behavior
(and I think that's a good thing).

It's got nothing to do with other languages.

Similarly, I would say "The default parameter mode is 'in'."
And "objects are variable by default" and "objects are not aliased by default".
