ViewPageTemplate must be in the view's namespace, and it magically
fishes out the view, view's context and request, and makes them
available in the TAL namespace. Otherwise you would have to pass
these arguments by hand. When using PageTemplateFile you would have
to pass the args like this:
pt = PageTemplateFile("file.pt")
result = pt(arg1, arg2, arg3=value, arg4=value)
Then the positional args would be available in the TAL namespace as args,
and the keyword arguments would be available as options:
<tal:block define="arg1 python:args;
arg4 options/arg4;" />
Arguably, the keyword arguments are a bit less ugly.
