O!! Thx man! This explains a lot. Never notice for yrs.
So I am gonna change my habit to do this way :
@arr = qw/Foo Bar Blaz/;
foreach ( @arr ) {
my $ele = $_;
$ele =~ s/^(.)/x$1/;
}
# or this
while ( my $ele = <@arr> ) {
$ele =~ s/^(.)/x$1/;
}
print "@arr"; # still 'Foo Bar Blaz'
Would you suggest which one is better, or any well suggested practice?

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).
