[$] 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.

PHP 8.5.0 released

Version 8.5.0 of the PHP language has been released. Changes include a new "|>" operator that, for some reason, makes these two lines equivalent: $result = strlen("Hello world"); $result = "Hello world" |> strlen(...); Other changes include a new function attribute, "#[\NoDiscard]" to indicate that the return value should be used, attributes on constants, and more; see the migration guide for details.

Clang 21 Delivering Nice Performance Gains On AMD EPYC Zen 4 With HBM3

One of the areas I've been meaning to run more benchmarks on this season has been for the recently released Clang 21 compiler. Back in September when LLVM Clang 21 was debuting I ran some initial benchmarks and found it to deliver some nice performance gains on AMD EPYC Zen 5 but then have been busy with other benchmarks/articles for expanding that testing. Recently with having some spare cycles and gratis access still to the Microsoft Azure HBv5 instance for AMD EPYC Zen 4 with HBM3, I ran some Clang 20 vs. Clang 21 performance benchmarks there for those wondering about any performance benefits of this new compiler release on Zen 4.
