Re: Overriding bless for inside-out object safety

Overriding bless is something I have attempted, see Overriding CORE::GLOBAL::bless. There are some caveats, particularly concerning precisely when the override takes effect. Admittedly, the purpose I was intending was not for production use, but in leak tracing.

I posted my conclusions here; I have not yet released an updated Devel::Leak::Object, but I may do at some future point.

Hope this helps

I was considering overriding it only for the current package, not globally, but the point in your conclusions about it needing to be done at compile-time are well taken. I went through a similar learning process overrriding `rand` for Test::MockRandom. The pod for that has a pretty good description of when and how such overriding needs to happen. -xdg Code written by xdg and posted on PerlMonks is public domain.
