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.

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?

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*
