Description

I have following simple test filter (just simple showcase):

@register.filter
def simplefilter(input,noexvar):
	return "Return"

Template systen won't run the filter (and won't throw any error) when I call it with noexistent variable like this:

{{ some_variable|simplefilter:noexistent_one }}

It's really a problem because I can't provide some default variable like this (which would be really cool feature by the way):

{{ some_variable|simplefilter:(noexistent_one|default:some_default) }}

When noexistent_one actually exists the filter will be runt without problems..

Silent failure of template variables is a design choice. We are currently discussing modifying that behavior on django-developers.
