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.


Thus spake the Lord: Thou shalt indent with four spaces. No more, no less.
Four shall be the number of spaces thou shalt indent, and the number of thy
indenting shall be four. Eight shalt thou not indent, nor either indent thou
two, excepting that thou then proceed to four. Tabs are right out.
