Yes, what you say about low-level C-like behavior vs. DWIM Perl-like behavior is sensible. But you have to bear in mind that the "default, typical usage" model in Perl is to proceed as if the specifics of various error conditions don't usually matter and you should be able to carry on regardless -- i.e. in the "generic" case you ignore error conditions, and only attend to them (with an extra line or few of code) when you feel a specific need to do so.

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).
