There are lots of differences, but a big one is its lack of a strong distinction between compile time and run time. From "Scopes for C/C++ Users" (https://scopes.readthedocs.io/en/latest/cpp_users.html):

> 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.
