Literally Ruby

I’ve long been a double-quote user and thought it odd that languages supported both that and a single-quote for string literals. Ruby though is a bit clever. A single-quote e.g. ‘literal text’ tells Ruby not to waste time looking inside the string. Double-quotes e.g. “Hello {#name}” tells Ruby that you want it to interpret the contents. In this case Ruby will replace #name with the variable’s value.

Forgive me if this is obvious, but single-quote 'just-a-string' and double quote "$variable interpolation" behavour has been present Perl for oh... ages, with and without curly braces. If I understand the history of Ruby aright, some Perl functionality made its way into Ruby. Which (as an occasional 'web programmer' dabbling in Ruby) I like.

Yup, JavaScript does it too (I think.) Going into the histories of what language pinched what feature from what language is crazy though.
