Defines a list of elements using only the boundary elements and allows for a more condensed representation of a n interval. The syntax is: lowerlimit..upperlimit where lowerlimit is an integer representing the first element in the list and upperlimit is an integer representing the last element. All other elements are generated by adding 1 to the current element.

The above example will just print out each of those values that are separated by a coma.

The range expression will iterate randomly over the range expression defined as an argument. The syntax is random(your_expression), where your_expression can be any of the already existing range expressions. Now this expression is a little trickier to use because since it will select elements in a random order it doesn't really have an end or a beginning so you want to use it carefully.

The above example will print out 5 randomly chosen elements form the expression defined in the random expression.

There is a simple way of aggregating ranges with the use of the square brackets. By wrapping an existing range expression in those brackets you create a sub-expression, like so: [expression1][expression2]. With this new syntax you can create ranges with fixed parts that iterate over a value of possible numbers. Like in the examples.

The above range would have the values client1,client2,client3...client10.
