I don't know if it is still possible.

You can always define a view class and use the return value of a function:

<browser:page
	template="the_file_above.zpt"
	class="pyfile.viewclass"
	[...] />

In your file pyfile:

class viewclass:
	def foo(self):
		return "bar"

and now you can use a TAL expression like that:

<span tal:replace="view/foo" />

is being replaced with:

bar

Hope that helps,
