Description
Migrated issue, originally created by Anonymous
When a template takes an argument like <%page args="x" /> and x is not provided, it yields the following error:
exceptions.TypeError: render_body() takes exactly 2 arguments (1 given)
I think we should add some more explicit reason of what's missing. Like "page.html takes exactly 2 arguments (1 given). Missing required argument x."

Research direction
Start by reproducing the <%page args="x" /> template case with the argument omitted and trace where the render_body() TypeError is generated. Done means the error identifies the template and explicitly names the missing required argument while preserving the existing argument-count information.
