@ChShersh Sure, but that‘s still not the same as real pattern matching. Can I deconstruct values and assign some to variables, while matching the values of others? Can I user regular expressions to match arbitrary strings?

Introducing the seamless Java/Swift interop effort! Offering both: - generated Swift macro based JNI wrappers - Project Panama based Swift accessors generated with a jextract-swift tool for high performance use-cases Early prototype is open source and we’ll share more about our plans and invite folks to collaborate early next week! github.com/swiftlang/swif… #ServerSideSwift2024

@ktosopl Yeah, future will be all digital… at least you can still buy the disc drive separately for now. Hope that remains the case for the next gen.

@dextroxin @HSVSphere The callee does not care if an object us heap or stack allocated, it‘s always just a pointer. The only time it accesses stack offsets directly is when arguments get passed on the stack, as part of the calling convention.

@dextroxin @HSVSphere That is not correct. The heap pointer would most likely be passed in a register, not on the stack. Same is true for the stack allocation as well. The callee may have the current stack pointer, but it does not know where the object is allocated, so you still pass a pointer to it.

@MatRopert What‘s the point of copy constructing an atomic? This would be a potential source of bugs as the new copy would reference different memory, but the whole point of atomics is to be shared. Moving without proper ownership model is equally problematic.

@ktosopl Love your sense for fashion. My seasonal changes are basically adding or removing layers 😅

@ktosopl This always amuses me. There is this notion of From games being incredibly hard to beat, let alone platinum, yet they usually have a very high platinum rate (>=10%). Are fans of From games just more dedicated to getting the plat?
