[$] Unpacking for Python comprehensions

Unpacking Python iterables of various sorts, such as dictionaries or lists,
is useful in a number of contexts, including for function arguments, but
there has long been a call for extending that capability to comprehensions. PEP 798 ('Unpacking in
Comprehensions') was first proposed in June 2025 to fill that gap. In early
November, the steering council accepted
the PEP, which means that the feature will be coming to Python 3.15 in
October 2026. It may be something of a niche feature, but it is an
inconsistency
that has been apparent for a while—to the point that some Python programmers
assume that it is already present in the language.
