No, because dataclass is the name of a class decorator ("This class is a
data class"), not the name of a type.

It's akin to "static method", "class method", and "instance method" for
function definitions (although the last one isn't a typical decorator,
since it's the default behaviour for functions placed inside a class).

Nick.
