Update of /cvsroot/python/python/dist/src/Parser
In directory usw-pr-cvs1:/tmp/cvs-serv8983/Parser

Modified Files:
      Tag: ast-branch
	Python.asdl 
Log Message:
Experimental change: Add Param to expr_context.

It's convenient to represent a function's parameter list as a sequence
of expressions, because they can contain names or tuples.  Rather than
re-using an existing expr_context for the names, make one explicitly
for this purpose.

There are some downsides: Must cover Param in all switch statements.
Param isn't used directly by the AST.
