Benchmarking it on my machine shows the multi line version running faster than the one liner.
use Benchmark;
@array = ('elementary school', 'blah blah blah', 'stuff', 'hello', 'ya
+y');
timethese(100000, {
'one line' => '&one_line',
'multi line' => '&multi_line'});
sub one_line
{
do {s/\s+/\t/; s/elementary/my dear Watson/g;} for @array;
}
sub multi_line
{
for ( @array ) {
s/\s+/\t/;
s/elementary/my dear Watson/g;
}
}
Output:
multi line: 5 wallclock secs ( 5.04 usr + -0.01 sys = 5.03 CPU) @ 19880.72/s (n=100000)
one line: 5 wallclock secs ( 5.72 usr + 0.00 sys = 5.72 CPU) @ 17482.52/s (n=100000)

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).
