To load this example and for sample queries, please see the `SCRIPT.txt`
file.

This example compares defaulty and tagged data representations using the
`ports_profiler` tool. The example defines both `defaulty` and `tagged`
objects implementing the same predicate. This predicate, `count_atomics/3`,
counts the number of atoms and the number of numbers in a list that can
contain atoms, numbers, and other types of terms that are irrelevant.
Running the same query for both representations, the `ports_profiler` tool
is used to highlight their performance difference.

For a detailed analysis of this example, see the following blog post:
