No, it can't be - parentheses are optional, and without them,
"(): [12]" and "{(): [12]}" would mean wildly different things. And any
programming language should aim to minimize and avoid such cases.
It's a similar concern which was raised for PEP642 (pattern matching
alternatives), where syntax looking related to sets, was suddenly
repurposed to mean dicts instead. Such cases are highly confusing.
