How to just get a list of command-line arguments in Crystal lang

Question

I'm a newbie in Crystal lang, and I just wanted to know how to get a list (array) of command-line arguments in Crystal. I am aware that there's OptionParser. But I just want to get a list of arguments users typed in.

ARGV is a Top Level Constant that contains all command line arguments.

Documentation can be found here: https://crystal-lang.org/api/1.3.2/toplevel.html
