    // This is the compiled bytecode for inputs/passing/projEuler/p28.ts.
    //
    // Using `RUSTFLAGS="-C opt-level=s" cargo build --release` it currently compiles to 534KiB.
    // A program with just println!("Test") is 315KiB, so we might be able to get down to around
    // 219KiB by simplifying the way we print the result.
    //
    // Since we're still in early development, the bytecode is subject to change, which means this
    // bytecode might break.
    //
    // If you need to fix it, or use a different program, use vstc:
    //     vstc compile program.ts
    //     vstc assemble out.vsm
    //     # Output is in out.vsb. Use the xxd program (or otherwise) to see the bytes.
    //

    //     cargo build
