I would like to be able to pass a list to the templates. See the two code blocks at the end of this post for an example. Right now it appears that if you pass a list in the config object, it's read as a list of options for that key.

I know that you can use str.split() in the jinja2 template, but that's not a real solution, since it's impossible to "escape" the character that's used as the delimiter. What's the best solution here? I would prefer to be able to pass a list in the json object and call it a day, but obviously that doesn't work for the user input prompts.

• cookiecutter.json:

{
  "build_steps": [
     "do_something",
     "do_something_else"
  ]
}

• Dockerfile:

FROM something

{% for step in cookiecutter.build_steps %}
RUN {{ step }}
{% endfor %}
