I suggest changing this to something like this:
class tag(object):
def __init__(self,name):
self.name = name
def __enter__(self):
print "<%s>" % name
def __exit__(self):
print "</%s>" % name
with tag('html'):
# ... etc.
So that it's obvious where the implementation is coming from. Otherwise,
it looks altogether too magical.
Also, the posted draft doesn't explain what happens to the __enter__ return
value, either in a literal sense or in the sense of where it fits in the
overall concept of context management.
