You can choose to use either refcounting or unique ownership for your types. For most use cases, refcounted (+ copy-on-write) is the best choice and is the default, but the truetyp…

I assure you, every inch of the interpreter code has been stared at by humans, a lot. TBH even the assembly generated by it has.

Python and LIT are used heavily to build and test the compiler, but that is only for building it, you do not need it to download and use the built toolchain. The python dependency …

The Swift toolchain includes LLDB, which relies on python for some debugging features. The compiler and runtime itself do not use python.

Swift, Rust, and C++ all share the same underlying techniques for implementing zero-cost abstrations (primarily, fully-specialized generics). The distinction in Swift's case is tha…
