Semantically, you are right.
But, that is not the issue Ovid raised in Recap: The Future of Perl 5.
In his proposal, Ovid seeks to reduce the number of required steps and simplify the syntax in Perl 5's OO system.
As to why I said Python's OO system seems to have changed since Larry stole from it, see the Python 3 example:
__init__ is called with an already "blessed" ref to an already allocated container. __init__ only sets values to the objects's fields.
The 1-to-1 translation to Perl would be (using signatures to reduce "noise"):
Even if we make __init__ more Perl-ish (still using signatures):
Ovid would still point out that Perl is requiring the programmer to perform 2 extra steps: Allocate the container and create a blessed reference to the container.
I don't know which version of Python Larry stole the OO system from, so I don't know what Larry changed. But, at least to me, Perl 5's classes look more like Smalltalk classes than Python 3 classes.
