I say disallow it. That is ambiguous as to what your intentions are even if you know what '*' does for multiple assignment. My real point was that the PEP lacks precision here. It should list the exact proposed changes to Grammar/Grammar.

You're right.

I tried to imply this with "A tuple (or list) on the left side of a simple assignment", but it isn't clear enough.

I'll update the PEP to incorporate the grammar changes today.
