Yes, it is a compile-time vs. run-time issue. You could enclose your require statement in a BEGIN{} block and do just fine.
As for your second question, you could have all your constants have a common prefix, like C_. Then, you can do a little introspection as so:
package Constants;
use base 'Exporter';
our @EXPORT = grep {
substr( $_, 0, 2 ) eq 'C_'
&& __PACKAGE__->can( $_ );
} keys %Constants::;
use constant C_FOO => 1;
use constant C_BAR => 2;
use constant C_BAZ => 3;
The Perfect is the Enemy of the Good.

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).
