Not quite. The first method does not assign to the same $_ that the while loop uses. If it did, you couldn't use $_ in that for loop at all.
while (<FH>) {
# localized $_
for (split ' ') {
# localized $_
}
# previous $_
}
It's when you start doing silly and dangerous things like:
sub foo {
$_ = shift; # TSK! local $_
tr/aeiou/AEIOU/;
return $_;
}
that problems occur. It is a bad idea to assign to a global $_ -- where "global" means "not localized".

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).
