I don't know why people want a verbatim 'switch' statement when you can use a for-statement.
#!/usr/bin/perl -w
use strict;
{
for (1..40) {
print;
($_ % 3 == 0) && print q! fizz!;
($_ % 5 == 0) && print q! buzz!;
($_ % 7 == 0) && print q! sausage!;
print "\n";
}
}
I generally use a for loop in conjunction with regular expression matches, like this trivial example:
#!/usr/bin/perl -w
use strict;
{
my @items = qw/The three principal virtues of a programmer are Laz
+iness, Impatience, and Hubris. See the Camel Book for why/;
for (@items) {
/^[A-Z]/ && do {
print "Found a proper noun? $_\n";
next;
};
/[,.]/ && do {
print "This word has punctuation: $_\n";
next;
};
print "This word seems uninteresting: $_\n";
}
}
It has a lot of flexibility where you can mix and match parts and get real nice uses out of it. I've always used it fully and got very good results --without waiting for a proper switch statement.

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).
