{$smarty.capture.$somevar} no longer works

[ymTm7KuhCnIjkZAl2x2m2]

The following code and output should display the issue.

Template:

Smarty: {$smarty.version|escape}
<br />
PHP: {$phpversion}
<br />
{capture name=FooBar assign=FooBar}I am the foobar{/capture} 
{assign txt 'FooBar'} 
1: {$smarty.capture.FooBar}<br />
2: {$smarty.capture.$txt}<br />
3: {$smarty.capture[$txt]}<br />
4: {$txt}<br />
<!-- just in case it's caps lock related --> 
{capture name=baz assign=baz}I am the baz{/capture} 
{assign txt2 'baz'} 
5: {$smarty.capture.baz}<br />
6: {$smarty.capture.$txt2}<br />
7: {$smarty.capture[$txt2]}<br />
8: {$txt2}<br />

Output:

Smarty: 3.1.27 
PHP: 5.6.36 
1: I am the foobar
2: I am the foobar
3: I am the foobar
4: FooBar
5: I am the baz
6: I am the baz
7: I am the baz
8: baz

Smarty: 3.1.33-dev-5 
PHP: 5.6.36 
1: I am the foobar
2: 
3: 
4: FooBar
5: I am the baz
6: 
7: 
8: baz

Please note that the Smarty special variables like $smarty.foo .... are no real variables and are not necessarily implemented as array. It is not specified that variable capture names can be used like
php $smarty.capture.$foo
However it did work unintended in some previous versions of Smarty

Access to variable capture blocks could be achieved by

{capture assign='bar'}
    buh
{/capture} 
 ....
{$foo}  // with $foo = 'bar'

Anyway I did add the variable capture name now as a feature
