Can smarty block names be derived from smarty variables

I would like to define smarty block names according to smarty data, but I can't seem to do it.
Example:

{foreach $array as $code}
  {block name=block_$code}
     <div id='{$code}'></div>
  {/block}
{/foreach}

My purpose is to extend a specific block_$code block by a child template. Is this possible or is there some other trick I could use to do this?

Thanks.

Solution

I was able to find the following link from 2011 indicating that this wasn't possible at that time. I suspect it still isn't:

The good news it that I was able to figure out how to make my code work without it. I wanted to be able to override just one of the divs defined by the foreach. Here's how I can do it:

Parent:

{foreach $array as $code}
    {block name=code_loop}
        <div>Normal Stuff</div>
    {/block}
{/foreach}

Child:

{block name=code_loop}
    {if $code == 'code of interest'}
        <div>New Stuff</div>
    {else}
        {$smarty.block.parent}
    {/if}
{/block}
