Why would this be cleaner? You've got a reference to an array, containing a hash, meaning it only exists 1 time in your memory.
Now you're dereferencing it into another hash, resulting in being twice in the memory. Do this with larger hashes over and over, and the memory usage becomes bigger and bigger.
Print city: $result->[0]{'city'}\n"; is a verry legitimate way to write the results, i'd like the iterative way even more, in $result->[1] may be another hash, so i'd use ikegami's approach:
foreach $record ( @{$result} ) {
foreach $field (keys %$record) {
printf("%s: %s\n",
$field,
$record->{$field},
);
}
print("\n");
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
