Ruby: The future of frozen string literals

In programming languages, literals are textual representations of values in the source code. This is a syntactical concept.

Some examples:

7 # integer literal

no Homebrew required

$ cd /usr/local/src
$ curl -OL http://nginx.org/download/nginx-1.12.2.tar.gz
$ tar -xvzf nginx-1.12.2.tar.gz && rm nginx-1.12.2.tar.gz

-#, --progress-bar Make curl display a simple progress bar instead of the more informational standard meter.

-b, --cookie <name=data> Supply cookie with request. If no =, then specifies the cookie file to use (see -c).

-c, --cookie-jar <file name> File to save response cookies to.
