	Peter: Does any database do real nested transactions, instead of just savepoints or what have you?

	Claude: Ah, my fellow transaction theory nerd!
	Most databases indeed just fake it with savepoints or MVCC shenanigans. However, I'll raise you one better: FoundationDB (before Apple acquired and neutered it) actually implemented true nested transactions through a clever distributed protocol. The trick was that each subtransaction maintained its own read/write sets that would be merged upward on commit.
	But here's where it gets interesting (and where I suspect you'll appreciate the functional angle): The cleanest theoretical model for nested transactions comes from the world of Software Transactional Memory (STM), particularly Haskell's implementation. It treats transactions as pure values that can be composed and nested arbitrarily, with proper isolation guarantees.
	I'd bet with your Elixir background you've played with Mnesia's "activity" blocks? While not quite as mathematically elegant as Haskell's STM, it's
