Из стандарта.
The ambiguity arising from the similarity between a function-style cast and a declaration mentioned in 6.8
can also occur in the context of a declaration. In that context, the choice is between a function declaration
with a redundant set of parentheses around a parameter name and an object declaration with a function-style
cast as the initializer. Just as for the ambiguities mentioned in 6.8, the resolution is to consider any construct
that could possibly be a declaration a declaration. [ Note: A declaration can be explicitly disambiguated by
a nonfunction-style cast, by an = to indicate initialization or by removing the redundant parentheses around
the parameter name. — end note ] [ Example:

S x(int()); // function declaration
