I should point out that my suggestion wasn't intended to be syntactic
sugar. Using the 'with' statement would (hopefully) allow embedding
other logic and objects in HTML helpers thereby allowing full
templating in Python. i.e.:
with DIV(_class='test') as d:
with TABLE(_id='mytable):
rows=db(db.mytable.myfield!=None).select()
for r in rows:
with TR(_class='datarow'):
with TD(r.title):
pass
Then you could build re-usable chunks of template code for views,
widgets, etc. You could also build base classes for your views and
inherit from them, overriding any part of the layout.
I'll kick it around a bit and see if anything interesting emerges.
