I’m using readlines() to get multi-line input with a non-fixed number of lines of user input from stdin, but I can’t get readlines() to stop taking input. I’ve tried alt+enter, esc+enter, shift+enter, alt+shift+enter, ctrl+enter, ctrl+D. How do I denote the end of my input? Thank you!

The VS Code REPL does not seem to handle `readline()` properly - [see this post](https://discourse.julialang.org/t/readline-cr-behavior/71317/4).

FWIW, using a standard Julia REPL the following code works for me on Win10 to terminate with CTRL+D followed by ENTER _(while the VS Code REPL misses the first input line)_:

```julia
function readlines_stdin()
    lines = String[]
    while true
        s = readline(stdin)
        Int(first(s)) == 4 && break # CTRL+D, then ENTER to exit 
        push!(lines, s)
    end
    return lines
end

lines = readlines_stdin()

```
