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

I used 'magic' markers, since I am lousy at coming up with new
keywords....

It might be that my proposal the same as the 'make' pep but not so
general...
But I'll try to formalize it a little bit more.

I am proposing two new keywords 'node' and 'attr'. Which have the
syntax:

node [callable|name][:]

This will append itself to the current node if it is a callable. If it
is a name it
will become the new current node. The current node has the scope of the
block
or until a new node is created.

attr name = expression
This will set the attribute name to expression on the current node.

I dont think it is the same as the  'make' but I wouldnt rule it
out.....
