      const gchar* first_property,
      va_list var_args
    )

#### Description [src]

Create a new `PeasExtensionSet` for the `exten_type` extension type.

Since libpeas 1.22, `exten_type` can be an Abstract `GType` and not just an Interface `GType`.

See `peas_extension_set_new()` for more information.
