The text you're quoting:
(NOTE: If FILEHANDLE is a variable and the next token
is a term, it may be misinterpreted as an operator
unless you interpose a "+" or put parentheses around
the arguments.)
applies to the print FILEHANDLE LIST form of print. More relevant for your print statement is:
Also be careful not to follow the print keyword with
a left parenthesis unless you want the corresponding
right parenthesis to terminate the arguments to the
print--interpose a "+" or put parentheses around all
the arguments.
Without the "+", you would have
print(split)[2], $, ;
which is a syntax error.

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).
