String Literals
A string literal represents a string constant obtained by concatenating a sequence of characters.
Interpreted String literals are strings of characters enclosed in double quotes, as in "bar". Between the quotes, any character can appear except newline and unescaped double quotes.
Text enclosed in quotes forms the value of the literal, with backslash escapes interpreted as they are in rune literals (except that single quotes are illegal and double quotes are legal), with the same restrictions.
fmt.Println('Hello, World')
// Will generate an error as single quotes indicate runes, not strings
