Calling a function using the -> syntax calls it as an object method.
Nope. -> has a double purpose:
- Object method call: $obj->meth(@params)
- Class method call: Class->meth(@params)
What the OP did, is applying the latter: invoking a function intended to be used as a function, as a class method. The result is that an extra parameter is unshifted, by perl, in the argument list, @_, before control is passed to it: the Class, which is a string.
He should try, with a higher chance of success, to call
Date::Calc::Add_Delta_Days($year,$month,$day, -3);

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).
