Well, everything is possible with a source filter :) (Sorry, only solution I could think of.)
package DynPackage;
use Filter::Simple;
use Text::Balanced qw/ extract_bracketed /;
FILTER_ONLY
code => sub {
1 while s/\bdyn_package \s+ ([^\n]+?) \s+ (\{.+)$
/ do { my ($pkgcode, $stuff) = ($1,$2);
my ($code, $rest) = extract_bracketed($stuff,'{}')
+;
qq|
{ \$DynPackage::pkg = $pkgcode;
eval "package \$DynPackage::pkg;" . <<' DYNPACKAGE_AUTOBLOCK';
$code
DYNPACKAGE_AUTOBLOCK
}
$rest
|;
}
/xes
},
# FOR DEBUGGING:
# all => sub { print }
;
1;
Later on...
use DynPackage;
foreach my $block ($self->get_blocks) {
dyn_package $block->package {
$block->setup->();
$block->code->();
$block->teardown->();
};
$self->_croak($@) if $@;
}

Are you posting in the right place? Check out Where do I post X? to know for sure.

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
