Is there a more straightforward version?
I don't know if you will consider it more straightforward, but the can() universal method can be used here (see The UNIVERSAL Class in perlobj). As the original example is a class method call, argument passing is, well, straightforward. Had it been an object method, the object reference would need to be passed explicitly as the first argument. (Update: See the reply of afoken for the correct way to invoke with class name or object reference.) Also be aware that if the method does not exist, can() returns undef.
>perl -wMstrict -le
"use 5.014;
;;
package Foo {
sub bar_baz { print 'i am bar_bazing! ', @_; }
}
;;
my $x = 'baz';
Foo->can(qq{bar_$x})->('Hooray!');
"
i am bar_bazing! Hooray!

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).
