This works for me:
unless(@lexlist){@lexlist = sort keys %lexicon};
I think what you're missing is that you can't use "or" in that way, not what happens to @_.
UPDATE:
Here's my test to prove that @_ is not always evaluated to true:
&lex();
&lex(1,2,3);
sub lex{
@lexlist = @_;
if(@lexlist){
print "I got the lexlist, here it is: @lexlist \n"
}else {
print "where's the list?\n";
}
}
Which answers your question.

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).
