I'm not sure what this one mean precisely.
The way I interpret it is that (for template constraints), they
are quite clumsy for specifying preferences between overloads,

Well, we are yet to define "static if" when it comes to tricky

"alias" supports two syntaxes, one of them specifically to
address writing things like alias A this.
That's inconsistent. I agree not the most urgent thing i

What kind of syntactical sugar do you feel is missing in D?
int square(int x)=>x*x;
Unfortunately we still can't just write:
alias square = x => x * x;

Dear community, are you ready for this?
Yes.
This is a significant change of behavior. Should we provide a
temporary flag or attribute to disable it?
I don't think so, it will just hinder adoption. If people don't

I'm thinking of relaxing the definitions to all types that

Welcome!
1. What is the current support for calling C/C++ free functions
from D? What level of mangling is supported? What data types
can be passed without translation from D to C/C++?
3. How can a C++ object be used from D? Can C++ methods be
called from D? The question applies to value typ

first: compilation speed. compiler can stop looking at function

No, it still has to check the other returns for errors anyway.
second: it's easier to human to determine the actual return
Consider these two functions:
auto ref foo(ref int x) {
if (condition) return x;
return 3;
}
auto ref bar(ref int x) {
return condition ? x : 3;
}
At a first glance, they appear to be equivalent, however foo is a
compile-time error "constant 3 is not an lvalue" while bar
compiles fine a
