I said that this was how I read that, and parens do matter here:
$ cat test.pl
#!/pro/bin/perl
use strict;
use warnings;
my $file = "/tmp/test20.pl";
-e $file and print "$file EXISTS!\n";
print "$0 \n";
- e $file and print "$file WILD!\n";
$ perl test.pl
test.pl
Can't call method "e" without a package or object reference at test.pl
+ line 10.
$
versus
$ cat test.pl
#!/pro/bin/perl
use strict;
use warnings;
my $file = "/tmp/test20.pl";
-e $file and print "$file EXISTS!\n";
print "$0 \n";
- e ($file) and print "$file WILD!\n";
$ perl test.pl
test.pl
Undefined subroutine &main::e called at test.pl line 10.
Enjoy, Have FUN! H.Merijn

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
