Hi,

The possibility to specify attributes without parentheses is a mistake
that we will corrected as soon as
possible. It was introduced together with the -spec and -type notation
which does not need parentheses.

I don't understand why it is cool.
Don't even try to use this syntax in your code you will be punished
with syntax error as soon as we fix this bug.
