in reply to Memory overhead of blessed hashes

Perl object memory overhead can be useful for benchmarking this in more depth.

Probably not your case but if these objects/hashes are constantly created, used and deleted, then forgotten references to them can stop the garbage collector from cleaning them up. Typical memory leak scenario.

It's not my code and I don't wanna get deeper involved as long as the stakeholders keep insisting on their voodoo technologies°

But while consulting I got into an argument with another very well respected member of the Perl community talking about "the non trivial overhead of bless magic" and I wanted to make sure I'm not missing any inner optimizations.
