in reply to Does this ctor make sense?

From bless:

bless REF,CLASSNAME
...
If CLASSNAME is omitted, the current package is used.

This works OK where there is no inheritance. But (from the same doc):

Always use the two-argument version if a derived class might inherit the function doing the blessing.

Otherwise, the derived class object will be blessed into the wrong class.

Update: If you have access to the Camel Book, see especially the section “Object Construction” in Chapter 12, pages 424–9 (4th Edition, 2012).

Hope that helps,
