Writing bless() yourself has only ever been advisable for low level code or as an optimisation for a couple of decades and most professional perl programmers are well aware of that. Generally you'd use one of the M* systems - p3rl.org/Moo or p3rl.org/Mojo::Base or p3rl.org/Moose - the last one having a full metaprotocol, the other two being rather lighter weight but still with enough features to keep you relatively sane. The new system is actually not that dissimilar to those in terms of the conceptual model even where the names and syntax are slightly different, so anybody who's been writing production OO code in the past ten years shouldn't have that much trouble switching across.
