By best, I suppose I really mean transparent. I have a module SomeModule.pm, which exports a function, ed(). It also has some helper methods that call ed(), as it does all the heavy lifting.
Now I have Inline::C code for ed() (added to the end of SomeModule.pm) and i'd like for the Inline::C ed() function to be exported and used by SomeModule.pm's helper methods if Inline::C is installed, otherwise export/use the Perl version of ed().
So I wonder what the best way to handle the situation is. Text::CSV_XS appears to set an env variable, but that doesn't seem ideal. Another solution uses eval { require Inline } and checks $@, but checking $@ doesn't seem ideal either (I see that in rare cases $@ gets modified).
Neither solution seems to be a very modern, elegant approach. What are some better ways to handle this?

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).
