Method dispatch mechanisms in Swift: static and dynamic dispatch (nilcoalescing.com)
Method dispatch refers to the process of determining which method implementation to execute when a method is called. In Swift, this can be either dynamic or static, each with distinct implications for performance and flexibility.

C++26 Expansion Tricks (pydong.org)
P1306 gives us compile time repetition of a statement for each element of a range - what if we instead want the elements as a pack without introducing a new function scope?

Rohlang3: A point-free, homoiconic, and dependently typed "SK calculus" (rohan.ga)
I’ve long been obsessed with minimalistic languages that still manage to have expressive power. My usual approach: start with a bare-bones combinator calculus (like SK), then keep adding “one more extension” until it looks suspiciously like a full-blown typed language. rohlang3 is exactly that experiment. It’s a small language built in Rust that tries to be point-free, homoiconic, and (somewhat) dependently typed, all on top of an SK-like foundation—plus reflection, partial evaluation, and a weird environment reordering system.

Go's Weird Little Iterators (mcyoung.xyz)
A second post on Go silliness (Miguel, aren’t you a C++ programmer?): in 1.23, Go finally added custom iterators. Now, back when I was at Google and involved in the Go compiler as “the annoying Rust guy who gets lunch with us”, there were proposals suggesting adding something like this, implemented as either an interface or a func:
