If your goal was to mimic the exact Python semantic, I'd try to patch or subclass Tie::Hash::NamedCapture to record the last name set.

> Internally %+ and %- are implemented with a real tied interface via Tie::Hash::NamedCapture

In a hurry I couldn't find the implementation, not sure if it was done in pure Perl or XS/C.

But even if in C, monkey patching STORE with a wrapper should do the job

update

Never mind.

I ran some experiments and couldn't succeed in patching STORE to any effect.

And according to the docs

> %- and %+ are tied views into a common internal hash associated with the last successful regular expression.

this wouldn't help either, because the internal hash is out of reach ... too bad.
