What distinguishes it from Rust and Swift?
> C/C++ requires programs to be built and linked before they can be executed. For this, a build system is typically employed.
> In contrast, Scopes’ primary execution mode is live, which means that the compiler remains on-line while the program is running, permitting to compile additional functions on demand, and to use other services provided by the Scopes runtime library.
> However, Scopes can also build object files compatible with GCC and Clang at runtime using compile-object, which makes it both suitable for classic offline compilation and as foundation for a build system.
