accessing an array element with a colon

[tacman]

I'm passing in a hydra json response, which includes an element with a key of 'hydra:member'.

My twig template is

<h3>
    {{ data['@type'] }}
</h3>
{% for d in data['hydra:member'] %}
{{ d.id }}
{% endfor %}

This throws an error

TwigException: Twig.expression.type.array.start cannot follow a Twig.expression.type.variable at template:4 near '[...'
ERROR Failed to compile with 1 errors Syntax Error: Unexpected token u in JSON at position 0
at JSON.parse ()

My solution is to set a temporary variable and use it, but I'm wondering if there's a better way, or if this can be fixed.

{% set hack = 'hydra:member' %}
{% for d in data[hack] %}
{{ d.id }}
{% endfor %}

Thanks. I think this library rocks.

Can you provide an example of it working as expected in Twigfiddle?

Indeed, I'm having a hard time reproducing it, or even finding where I used it in my code. Thanks, if I find it I'll reopen.

Please reopen this issue, since I've only provided the examples.
I've submitted a PR that could fix this issue, although I'm not sure if it will break anything else.
