So string eval works so long as the entire trailing code block is in the string, which gets pretty clunky for one scenario I'm dealing with. But it works, which is better than I've gotten on my own.
#!/usr/bin/perl
use strict;
use warnings;
use Data::Dumper;
my @data = (
{unit => 'S',
value => 50,
},
{unit => 'T',
value => 60,
},
{unit => 'Q',
value => 70,
},
);
LOCAL_BLOCK: {
my $cmd;
$cmd .= "local \$data[$_]{unit} = 'S';\n" for 0 .. $#data;
$cmd .= 'print Dumper \@data';
eval $cmd;
}
print Dumper \@data;
I'll do some digging on the cited modules, to see if they work in my context.

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).
