πŸ’– NAME πŸ’–

ok so bestie, meet Class::MOP::Class::Immutable::Trait β€” it's the thing that implements immutability for metaclass objects. that's the whole vibe. 🧊✨

🌸 VERSION 🌸

this is version 2.4000, ok? don't come for me with an older one 🫢

πŸ¦‹ DESCRIPTION πŸ¦‹

okay so here's the tea β˜• β€” this class is a pseudo-trait that gets applied to immutable metaclass objects. and the way that "trait" is doing so much heavy lifting... because lowkey? it's not a trait at all. in reality, it is simply a parent class. πŸ’€ like, that's it. that's the plot twist. it's giving "fake it till you make it" and honestly? it ate.

what it actually brings to the table is caching and read-only-ness for a whole bunch of metaclass methods. so once your metaclass is frozen 🧊, this is the thing making sure nobody comes along and tries to change stuff. iconic behavior, no cap. πŸ‘‘
