Typically when i code a function, i often times need a 'temporary variable', to preform a few operations on, or simple for the sake of neatness and stuff. Looking at perlvar, one might assume that $_ would be a perfect variable to use for this. The problem then comes in is that $_ is global, and if your function modifies it, that could cause a very, very nasty bug, espcially combined with things like map{} and for{}. So what is your wisdom on temporary variables, and $_ in specific. (I realize i could just do local($_); but i might as well just do my$foo then)
And while i'm meditating on semi-random things, does anyone else feel the need for another special var that would contain eithr the value, or a ref to, the last variable you used? Think of the fun you could have with it..

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).
