I’m referring to this part of the proposal:

"Additionally the standard library has approximately a half a dozen locations where optionals are compared to non-optional values which will need to be updated to explicitly cast one operand to an optional.”

I’m just saying that the internal implementation details of the standard library are typically considered part of an evolution proposal, only the public API impact.
