I really like the new 5.8 option in swift to run code directly from the command line. I noticed there is not much documentation so I wrote a post to promote this new feature and mention some interesting aspects. Hope this is helpful.
My comment about "not much documentation" was related to promotional material that this feature exists and how/when it can be useful. Also, I thought it's a good reminder that multiple statements can be used on a single line when using a semicolon as a separator.
