Cut your allocations in half with this one weird trick 😂

If you want to explore, the code is here: gist.github.com/tenderlove/0... The trick is that the multi-assign returns an array, and it can't be elided because initialize returns it (even though `new` ignores it)

Thanks, I've become very fond of Ruby's end-less methods and having to put the nil....

Is the return value of initialize ever used? Could it just always be forced to be elided?

It could be. You could just call it as a method and use the return value

Still feels like 99.999% of all uses is from .new, so seems ok to hard return nil in the VM, eliding the return. There's already precedent for it with setter methods that end in `=` not honoring the method's return value.

That's on the caller's side though. You can use send(:blah=) and it'll return the callee's return value
