Yes, but coderef2text is not executed when B::Deparse is loaded via O. In fact it's purely a wrapper around the subroutine deparser code, intended to be used at runtime, so Randal is correct (given his use case). >> coderef2text does not dump closures. I wish it would.

Hugo decides) a global flag "deparse closures with constants" that isn't set when B::Deparse is executed via O. I agree that this doesn't seem difficult to fix. I may have a look at it in the future, for some value of "future". (You know, when you discover something in perl that doesn't work as you think it should work, there's that perlbug thing in your $PATH.)
