Dear Monks, I was golfing around with ways to make perl print
its own source and came up with something odd. I would expect
the following program to print the first line of itself but
it prints the entire file. Why does it do that?
#!/usr/bin/perl
use strict;
use warnings;
print do{@ARGV=$0;<>};
My path thru this course:
print do{local(@ARGV,$/)=$0;<>}; # the usual idiom
print do{@ARGV=$0;local$/;<>};
print do{@ARGV=$0;$/='';<>}; # bad
print do{open$_,"<$0";<$_>};
print do{@ARGV=$0;*/;<>}; # wtf
print do{@ARGV=$0;<>}; # wow

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).
