Nice post: ++. Experimentation is a good way to test your theories. Of course, digging around the documentation can also be useful. Glancing through perldoc perldata yields:

Perl has three built-in data types: scalars, arrays of scalars, and
associative arrays of scalars, known as "hashes". A scalar is a single
string (of any size, limited only by the available memory), number, or
a reference to something (which will be discussed in perlref). Normal
arrays are ordered lists of scalars indexed by number, starting with 0.
Hashes are unordered collections of scalar values indexed by their
associated string key.

When your only tool is a hammer, all problems look like your thumb.
