The wrapper in Tie::Subset::Hash is a new variable.

I wanted to be able to tie the original variable while changing the original data.

This creates a lot of headaches to even access that data, to avoid recursion and related warnings.

Consider debugging, setting watchpoints, tracing, meta programming,...

It's not always possible to replace the monitored variable with a proxy, you just want to attach the magic directly.

There is code in the OP.
