Summary: 'Expression' AST Node not documented

Initial Comment:
Python 2.4.1 documentation
===
The table at the end of section "19.3.1 AST Nodes" 
does not list Node type 'Expression' and its associated
information.

Also, the BNF for 'expression' shown in the file
<http://docs.python.org/ref/grammar.txt>

> expression ::= 
>              or_test | lambda_form

can't be correct because it doesn't cover cases of a
simple literals (or identifiers) such as 42 and simple
binary operator expressions such as 1+2.

I have submitted a (very minimal) doc-patch that adds
expression to the section 19.3.1.

To your second comment: the BNF for expression is correct
since or_test can contain and_test which can contain
not_test and so on until primary, atom, literal.
