As I understood things, tye and you said Perl did the locking for the programmer when it came to the state of the SV. . Now you're saying I need to take locks myself.

Now who being ... What was that word you called me?

Perl takes care of protecting any internal changes.

Ie. refcounts; flags; SV upgrades; UTF upgrades; anything that is not (normally) changed directly by the programmer.

Eg, all 3 things you cited in your original post and many more.

The programmer is responsible for locking the variable itself.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
