Quoting

The usage of a semicolon to represent expressions is known as quoting. The characters inside the parentheses after the semicolon constitute an Expression object.

How to do it...

To check this behavior, let's check for the type of a similar statement that has an object inside the parentheses after a semicolon. This can be done in the REPL as follows:

typeof(:((a + b) * c) / 6))

The preceding command gives the following output:

Multiple expressions can be represented as a block by quoting them. The syntax would be as follows:

exp = quote
              some code
              some more code
              more code
              a little more
              ...
           end

An example with some code inside the code block would look like this:

Now, let's verify the type of the exp variable with the typeof() function.

So, the the code block enclosed inside quote and end is indeed an expression.

How it works...

Quoting is the concept of creating expression objects using the : character...
