No; look at the expanded form for a more readable (but syntactically
identical) version:
doc.add(
Tag('DIV')
.add('hello ')
.add(Tag('B').add('world'))
)
'world' is below Tag('B') - look at the parentheses - but
Tag('DIV').add('hello ') returns the DIV, not the hello, so B and
hello are peers.

They can be directly combined, because Tag.add(self,other) returns
self, not other.

Hmm. So when that gets added into a DIV, it has to get parsed for
tags? How does this work? This seems very odd. I would have expected
it to remain as DOM objects.
What happens if I do, for instance:
'blah blah x<y: '+B('True!')
I would expect B('True!') to mean the word "True!" in bold; what
happens with the angle bracket in the text? Am I supposed to manually
escape that as < to protect it? If so, your library isn't doing
much - B might just as well be defined as
lambda s: '<b>'+s+'</b>'
rather than any sort of class.
