Ever since Swift has debuted, there’s been a bit of a fuss about how it can be used for scripting. Yes, yes it can, but so can every other language that has an interpreter, or more accurately, a binary that can do something with the input file.

In fact, we can even make such a thing for C.

I already knew this but it might be a neat little trick for someone not as familiar with how all this stuff works under the covers.
