It's explained reasonably well at the top of the "perldoc perlclass"
documentation in Perl 5.38:

  History
    Since Perl 5, support for objects revolved around the concept of
    *blessing* references with a package name. Such reference could then be
    used to call subroutines from the package it was blessed with (or any of
    its parents). This system, while bare-bones, was flexible enough to
    allow creation of multiple more advanced, community-driven systems for
    object orientation.

    Class feature is a core implementation of class syntax which is familiar
    to what one would find in other programming languages. It isn't a
    "bless" wrapper, but a completely new system built right into the perl
    interpreter.
