Is it really scripting or just feeding the code into the swift cli which then compiles it? I recall writing Swift scripts also, and when feeding it into the swift cli, there was some time delay that was comparable to compiling the program. Whereas something like Python or JS is nearly instant when running a script, the swift cli would take some type before the computation would happen.
