I wonder if each variables with ext magic has its own virtual table pointer.

See SvPVMG & SvPVLV at PerlGuts Illustrated. It's probably somewhat out of date due to the 5.9/5.10 changes, but it is still the clearest guide around.

As I say, for my purposes, the SvPVLV and the associated 'x' type magic would pretty much do everything I want, provided I can adjust the LV_ARGS.

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.
