202	Markup should be interoperable with other stuff	ianb@…	cmlenz	"The Markup class can't be interoperable with other classes.  Specifically in WebHelpers we want to implement our own HTML literal class, basically equivalent to `Markup('<tags>')`.  Our object has a method `.__html__()`, that both indicates the object is a literal, and can be used to give an HTML representation of the object.

To work with this, Markup.escape would have to test for this attribute.  Right now it does an exact class check (even subclasses won't work).  We can't even do any kind of conditional mix-in.

If the Markup class also provides an {{{__html__}}} method, we could also support using Markup as a way of providing HTML literals in our own quoting code.

Also, `Markup(0) == ''`, while `Markup(1) == '1'`."	enhancement	closed	major	0.5	Template processing		fixed		ianb@… ben@…
