I think you should have to use the ternery
operator here:
my @lexlist = @_ ? @_ : sort keys %lexicon;
Update - contrary to glancing, || as well as
or will not work in this example. By using || or or
with parentheses, sort keys %lexicon is
evaluated in scalar context. Here is some code to
demonstrate:
use strict;
use Data::Dumper;
my %lexicon = (
foo => 'bar',
baz => 'qux',
);
foo();
foo(qw(one two three));
bar();
bar(qw(one two three));
baz();
baz(qw(one two three));
sub foo {
my @lexlist = @_ ? @_ : sort keys %lexicon; # correct
print "foo:\n", Dumper \@lexlist;
}
sub bar {
my @lexlist = @_ || sort keys %lexicon; # incorrect
print "bar:\n", Dumper \@lexlist;
}
sub baz {
my @lexlist = (@_ or sort keys %lexicon); # incorrect
print "baz:\n", Dumper \@lexlist;
}

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).
