Proposal for new operators to python that add syntactic sugar for hierarcical data.

I'm answering two of you posts here...

My code was  just to show that the proposal is not only for HTML
generation but could be used whenever you want to create COMPLEX
hierarcical datastructures.
In the above example I would of course use what you wrote.

Do I need to show you a example where you cant use the style you
showed?

Strange enough once almost anyone managed to get by without Python...

It not your fault :-)

You seem to really have a thing for Perl...

>From what you written I assume you mean that it is no good because you
find the syntax cryptic. For me cryptic is for example how you in Perl
create list of lists, ie
it takes a while to understand and when you havent done in a while
youyou have to relearn it. Python has a few of those aswell... but you
really
only need them when doing something cryptic...

IMO what I propose isnt cryptic, because of
  * I think after it has been explained it is no problem to understand
how it works.
  * It doesnt have strange sideeffects
  * Doesnt break any old code.
  * You dont have to relearn if you havent done it a while.

Also if you never would have seen such code before, I think you would
understand
what is meant and even be able to modify it.
