[literal] or 'literal' or "literal"

Brackets can be used to delimit a literal as wall as single and double quotes. Parens can indicate functions and to denote the use of a variable's value. Brackets can also bu used for array elements like laFile[1,2]. I just like to use different variations in my code samples as a subtle reminder that there are many ways to use brackets, parens, quotes and double quotes.
