Could you elaborate a bit more, please? I'm interested.
Some people in the D community has for a long time wanted
stack-less coroutines. This is now available in C++20, and maybe
D can borrow the C++ implementation for LDC? That is an
interesting possibility for sure.
"template metaprogramming only capable of being understood by
mensa member": some aspects of C++20 metaprogramming is easier
than D
That would me interest, too!
The main addition for C++20 is concepts. Basically wrapping up
ugly tests in a simple template parameter type specifier so that
you can specify that a template parameter MUST support Addition
or be a Stack or whatever you want to require with very simple
syntax. (It also makes it easier to specify tests.)
Btw, did D ever get to add nested template parameters? I know
people asked for it a long time ago, but cannot remember if that
was resolved somehow?
Just to say, I think not including multiple inheritance was a
mistake for Java and all its descendants, though not a big one.
Multiple inheritance needs just a good convention, that's all.
I almost never use multiple inheritance myself, but if you don't
use it, it does not affect you at all? So how could it be a
problem to have the option? *shrugs*
