Streaming templating languages for use as WSGI body.

[Alice Bevan–McGregor]

Not sure if it's bad form to respond to your own posts, but here goes.  ;)

Coding up a quick hack of a templating engine, I've produced this:

(The implementation of the engine itself is a base class that overrides 
__call__ and __getitem__, with __unicode__ serializing in one block, 
the norm for templating engines, and .render(encoding='ascii') 
returning a generator using cStringIO for internal buffering.)

I even have a light-weight widget system based on it, now.  E.g.

> class Input(Widget):
>     type_ = None
> 
>     @property
>     def template(self):
>         return tag.input (
>                 type_ = self.type_,
>                 name = self.name,
>                 id = self.name + '-field',
>                 value = self.value,
>                 **self.args
>             )

I'll polish it and package it up.  :)
