SE-0531: Literal Expressions

Ah, that's a great example of an ABI break. I missed that.

When it comes to ABI and API stability questions, I think it's a good baseline to start by assuming that:

• @usableFromInline declarations are effectively public
• @inlinable and @export(implementation) function bodies are effectively code from a different module

Ah, yes, so the same issues apply to @export(...) here...
