[$] 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, butthere has long been a call for extending that capability to comprehensions. PEP798 ("Unpacking inComprehensions") was first proposed in June 2025 to fill that gap. In earlyNovember, the steering council acceptedthe PEP, which means that the feature will be coming to Python3.15 inOctober2026. It may be something of a niche feature, but it is aninconsistency that has been apparent for a while-to the point that some Python programmersassume that it is already present in the language.
