# Feature or enhancement ### Proposal: Per PEP 667, `frame.f_locals` is now a write-through proxy (`FrameLocalsProxy`) for underlying fast local variables. In the beginning we did not implement the `copy()` method because we think `dict(frame.f_locals)` is a more explicit way to achieve the snapshot. However, there are existing code that's using `frame.f_locals.copy()` to take a snapshot. Moreover, `types.MappingProxyType({}).copy()` returns the copy of the underlying mapping so it's not unprecedented for a `proxy.copy()` to return a dict. Thus, we should implement `copy()` method for `FrameLocalsProxy` and make it return a dict of snapshot of the current local variables. ### Has this already been discussed elsewhere?
