   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 truetype interpreter made extensive use of non-refcounted types to

   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 is more about its use in LLDB.

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

   > The big performance hit in Swift would come in method dispatch where it’s following Objective C strategies which would result in indirect calls for object methods. While Swift can use Objective-C's message sending to communicate

   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 that generics can also be executed without specialization
