I'm sorry, Moose is a pig. Its startup time is atrocious. Its run time overhead is non-trivial. People who use Moose in my experience just showboat that they can do OO. Does it help? Maybe. But what it surely does is it makes a program run and startup significantly slower.
Things have moved on. Moose is a bit of kitchen sink. These days you would generally choose Moo first unless you really needed the meta object features. Or to get incremental Moo(se) features you’d use Role::Tiny, Class::Method::Modifiers And Type::Tiny
