Ah, you need to know about PT call signatures.  Page Templates aren't
like DTML; It is neither required nor useful to pass the client and
request.  All keyword arguments in the call are collected as a
dictionary in a variable called 'options'.  If there are positional
arguments, they are placed (as a list) in 'options/args'.

So, you could use:


return container.newtemplate(pagedict=pagedict)

tal:define="global pagedict options/pagedict | here/pagedict"

They're exactly the same, yes.
