I have some code which looks like this:
foreach my $block ($self->get_blocks) {
my %data = map { $_ => $block->$_ } qw/
package
code
setup
teardown
/;
eval <<" END";
package $data{package};
\$data{setup}->();
\$data{code}->();
\$data{teardown}->();
END
$self->_croak($@) if $@;
}
Frankly, I don't like the eval there because it obfuscates the code and breaks syntax highlighting. What I really want is something conceptually similar to this:
foreach my $block ($self->get_blocks) {
package $block->package;
eval {
$block->setup->();
$block->code->();
$block->teardown->();
};
$self->_croak($@) if $@;
}
That's much easier to read and it's regrettably a problem I face all of the time. Is there an easy way to force code to run in a different package when I don't know the package until runtime?

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).
