Create a helper like simple_tag that sets the context

[slowness chen]

If there are many places in which you need to use inclusion_tag , it gets annoying that you have to extract all these *short and simple* snippets into separate template files.
If simple_tag can also set context, that will be more convenient. for detail see ​http://groups.google.com/group/django-developers/browse_frm/thread/3c4f8112341038d7/b791042941e34904?hl=zh-CN#b791042941e34904

I agree with the idea behind this ticket (having an easy way to set the context), but I don't like the implementation. Having the decorator behave differently depending upon whether the return value is a string or a dictionary is not very Pythonic.

We should create a separate decorator for setting the context. If we can do this without duplicating all the code behind simple_tag(), that would be ideal.

So I'm not going to apply this patch (and removing the keyword, since the patch is not valid), but I'm leaving the ticket open, since it's a useful idea. There are slightly higher priorities at the moment, but we should eventually implement this.

I'm going to close this in favour of #1105. Once we can pass the context into a tag function like this, the programmer can set it and return and empty string if they want to.
