"I cannot imagine a case where I personally would want to use this language feature ..."
Well, for one, this feature is extremely useful when
'slurping' an entire file into a scalar. To do this, you
must set $/ to an undefined value, but doing that
could break client code. By only 'reseting' that variable
inside a 'bare block', you guarantee that you will not
break someone's client code that might use yours. In
action, instead of using:
my $data;
while (<FILE>) {
$data .= $_;
}
I can safely 'turn off' $/ temporarily via
local:
my $data = do {local $/ = undef;<FILE>};
# $/ contains it's original value (\n) now
But ... i have been coding Perl for a good solid 4 years
now. Your milleage may (and will) vary. I hope you decide
to stick around, because we have lots of useful information
for you. We just sometimes have to question why someone
would even want to do something like this, that's all. :)

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).
