-.. index:: pair: extended; slicing
There is ambiguity in the formal syntax here: anything that looks like an
expression list also looks like a slice list, so any subscription can be
interpreted as a slicing. Rather than further complicating the syntax, this is
disambiguated by defining that in this case the interpretation as a subscription
takes priority over the interpretation as a slicing (this is the case if the
-slice list contains no proper slice nor ellipses). Similarly, when the slice
-list has exactly one short slice and no trailing comma, the interpretation as a
-simple slicing takes priority over that as an extended slicing.

+.. XXX is the next paragraph stil correct?
The semantics for a simple slicing are as follows. The primary must evaluate to
a sequence object. The lower and upper bound expressions, if present, must
