[swift-evolution] The great renaming and the state of new Unified Logging in Swift

[Zach Waldowski]

For a wrapper, are there any public hooks into dyld that allow us to do
anything meaningful with #dsoHandle on prior OS? Without that, and
without using #dsoHandle, wrapping os_log is essentially useless.

Cheers!
