for the additional reference, the forum discussion is here:
https://forum.dlang.org/thread/rdrqedmbknwrppbfi...@forum.dlang.org
Now both Java and C# did it more correct than D.
"""
At least I want a warning message,

FWIW, in C# this is an error:
long a = -5000;
ulong b = 2;
long c = a / b; // Operator '/' is ambiguous on operands of type 'long' and
'ulong'

(In reply to mw from comment #2)
> BTW, on Windows, dmd correctly output -2500.
Not on Windows, but for 32-bit targets, as an unsigned 32-bit int is converted
to a signed 64-bit long in that case, according to spec

OK, let me write this in this way to show it's impact:
==
import std.algorithm;
import std.stdio;
void main() {
long[] a = [-5000, 0];
long c = sum(a) / a.length;
writeln(c);
}

Just because C++ did it doesn't means it's correct.
And D supposed to be an improvement of C++.

It can NOT silently do this, at least a warning.
BTW, on Windows, dmd correctly output -2500.
