I haven't looked at that code recently, but I believe the ADSL
sequence in the assignment node is for statements where there are
actually multiple assignment targets, such as:
>>> p = x, y = 1, 2
>>> p, x, y
((1, 2), 1, 2)

Ah I see. A quick test verifies exactly this:
>>> import _ast
>>> ast = compile("p = x, y = 1, 2", "<string>", "exec",
_ast.PyCF_ONLY_AST)
>>> ast.body[0]
<_ast.Assign object at 0xb7d0122c>
>>> ast.body[0].targets
[<_ast.Name object at 0xb7d0124c>, <_ast.Tuple object at 0xb7d0128c>]
>>> ast.body[0].value
<_ast.Tuple object at 0xb7d0132c>

I thought this would have been implemented as nested Assign nodes, but
I'm obviously wrong. :) Thanks for the clarification.
Cheers,
