A long time ago, I saw the first bits of Swift be used for the Swift compiler, looked cool.
Then I blinked for a second, and a massive chunk is now written in Swift!
Pretty sweet.

@MigueldeicazaMiguel de Icaza ᯅ🍉 If we’re doing our jobs well, nobody will ever notice that we’re doing this. But it’s making things cleaner and more robust and so much nicer to work on, bit by bit. You pointed at the optimizer bits; we’re also doing new-parser and related work over in https://github.com/swiftlang/swift/tree/main/lib/ASTGen.
