	It sounds like even if the buffer doesn't stream directly, it wouldn't
be hard to replace it with one that does.

	It certainly sounds like it would be faster.

	Mako is designed to look almost exactly like normal Python, which would
actually, for most people, be *less* syntax to learn. For example:

	http://www.makotemplates.org/docs/syntax.html#control-structures

	Also, I would say that the syntax of SimpleTAL is difficult to read,
particularly because so much happens inside of attributes. There are
some advantages to SimpleTAL, though, such as enforced HTML validation
and simple HTML escaping.

	The View/Annotation page actually responds significantly faster when it
can stream than when it doesn't. So streaming would be a useful and
important feature.
