> the two bigger things I did they have talked about but probably won't do is i made the class monitor opt-in https://dlang.org/changelog/pending.html#dmd.monitor-field

My understanding is that RC is relatively expensive in time (especially for atomic RC) but uses a lot less memory than state of the art fast GC. And RC doesn't handle cycles.

D doesn't store capacity in each slice. This allows a slice to fit in registers more often. Instead for GC allocated slices, the GC will store metadata before the first element of …

Because Go designers don't like OOP and didn't want low-level system programming as core features. They also were not keen on generic programming. Basically they wanted a simpler l…

This compiles: ref ubyte[n*2] requires_ptr_twice_as_large_as_input(uint n) ( const ref ubyte[n] input, ref ubyte[n*2] output, ) { output[0..n] = input[0..n]; output[n..2*n] = input…

Why is your proposal better than this: import std.sumtype; void main(){ struct A { int a; } struct B { string b; } struct C { bool c; } alias TaggedUnion = SumType!(A, B, C); auto …

Class instances can go on the stack too using `scope`: scope obj = new Object; ... // destroyed at end of scope

Arrays and slices really have nothing to do with generic programming. Java has poor generic support (type erasure) and C++ has poor syntax and a bad design for iterators. Languages…

Lack of generics does not ease development speed. Generic programming is about safe reusability. (Development speed includes the test, debug, fix cycle). No generics actually harms…

C's preprocessor means C code can often do interesting tricks, such as the X macro: http://www.drdobbs.com/the-new-c-x-macros/184401387 There are tons of other interesting uses for…

None of those things cause as much greenhouse gas emissions as a high meat diet. The level of meat consumption in rich countries is unjustifiable.

> C++ has the best (imperative) language support for templates D's template support is far superior: static if, constraints, compile-time function execution, string mixins, opDispa…

Actually it is simple: eat less meat. Meat production is vastly more wasteful than vegetable production calorie-for-calorie.

The problem is it's no better than C - the correct way is to return sum types, either values or errors. A good language would statically check that any returned values are only use…

> D's garbage collection is global, and either off or on That makes it sound like you can't use GC and manual memory management together; you can - std.container uses manual memory…
