    1. disassembler is working in REPL! here's a comparison between machine code generated by stock clojure compiler and magic ✌🏽

    just for fun here it is with the LLVM backend enabled 😮

      mono's llvm backend is really fucking good

        there's two things at play here: 1. clojure's IFn interface boxes all its arguments by default 2. even invokePrim, the type hinted method behind IFn, does not emit intrinsics, but static method invocations. note the call in the stock version

          the design of the compiler is based on the JVM implementation which can reliably depend on a runtime JIT to clean this kind of thing up, but that does not exist on the CLR. that's why magic prioritizes avoiding boxing and emitting intrinsics above all else.

            the approach *really* shines in the face of non-primitive value types, e.g. vector addition. the stock compiler's signature is object,object forcing it to unbox, while magic is able use the correct types and allow the LLVM backend to give us fast SIMD machine code
