Variables in for/block tags fail to render

[drmidnight]

I'd like to nest variables in tags, however doing so causes the page to not render.

Examples

ex1:
{% for type in types %}
    {% for file in {{type}} %}
      {% include "example.stencil" %}
    {% endfor %}
{% endfor %}

ex2 base.stencil:
{% for type in types %}
    {% block {{type}} %}{% endblock %}
{% endfor %}

# then in another template
{% extends "base.stencil" %}
{% for type in types %}
    {% block {{type}} %} 
        {% for file in files %}
            # lots of html here
        {% endfor %}
    {% endblock %}
{% endfor %}

Both ways don't seem to work right. I need the templates for my project to be completely dynamic and "types" can be anything.
Any thoughts on a way to accomplish this?
Using 0.9.0

@drmidnight can you try to explain again what you expect? In the first example, if types will be [["A", "B"], ["C", "D"]] you expect second loop to recognise inner array and do iteration over their elements?

This is not possible. In your first example you should use type without {{ and }} in for tag. Your second example will not work as block tag does not resolve runtime variables. Also it's not supported to define blocks in a loop.
