The following code puzzles me
#!/usr/bin/perl -w
use strict;
my %hash;
$hash{"key1"} = "value1";
$hash{"key2"} = "value2";
$hash{"key3"} = "value3";
# (1) this works...
my %inverse_hash;
%inverse_hash = reverse(%hash);
print keys (%inverse_hash);
# (2) this does not
print keys (reverse (%hash));
Why does (1) work and (2) not. Both seem to do the same.
Sniplet (2) gives the error; "Type of arg 1 to keys must
be hash (not reverse)", however doesn't reverse return
a hash?
Have Fun

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).

are good places to start.
