Description
These operators are unable to reuse resources if their output and input types are the same. There are plenty of settings where this can be true, but the current APIs seem to make this not possible (by only revealing a reference to the streamed input).

Research direction
Start by locating the Rust implementation of half_join and the API that exposes the streamed input as a reference. Determine how RefOrMut could permit resource reuse when input and output types match, and define tests that demonstrate the intended behavior.
