Feature proposal

This would aid in debugging and diagnostic scenarios. It would allow methods to capture the expression passed to a method for diagnostic purposes.

This should be updated in a few places:

  • Where diagnostics are covered
  • Attributes understood by the compiler.
  • nameof expressions should point to this new feature.

Note: The feature was implemented for Visual Basic as well (currently it's hidden under a feature flag). As soon as the feature flag gets removed, it should be documented for VB.
