Description
The HLSL standard committee is considering adding support for auto return types for normal functions (as implemented in C++14).
We should add this feature to DXC since it seems like an obvious extension over basic auto which we've already added as an extension.

Research direction
Start by reading the HLSL TC57 proposal at https://hlsl-tc57.github.io/tc57/proposal/0010/ and reviewing how DXC currently implements basic auto as an extension. Use the proposal to define the normal-function return-type behavior, then verify that the implementation matches the specified cases.
