Hi Eric, thank you for reply.

" But it's already there in most of the OSes !!" => On Windows (I'm a Windows user) and macOS, it is another story, trust me :)

"BTW I suppose that each executable embeds the interpreter," => I was thinking the same before trying these tools, but NO! The interpreter is not embed, you can confirm it with the size of the executable, a few MB for the simple "Hello World" program I used in the example. I don't know the details, but they take only part of the interpreter useful to run the program.

Docker is a great solution for api / web stuff, but if you want to distribute a CLI-first solution, it is nto the best solution IMHO.
