Twig用变量[TWIG / PHP]设置变量名

Question

How can I set a variable's name with the value of another value in Twig? I would think that It would go something like this:

{% set queCount = loop.index %}
{% for row2 in answer+queCount %}

But this does not work. Also making a string from that will break the loop (because it does not search for a string).
I know how to do this in PHP so for clarification, this is what I would like to achieve:

$count = 1;
$args["answer$count"]

which returns

$args["answer1"]

But this time, not with strings but the operant answer.

Thanks in advance!

You can use the _context variable

{% set queCount = loop.index %}
{% for row2 in _context['answer' ~ queCount] %}

Here is the doc about _context and global variables
