It depends on what you want. But you can always use composition instead of
inheritance for B. I have been using things like alias this, mixin and

You should open an issue on https://issues.dlang.org/
until it is fixed you can use lazy variation byChar, byWchar or byUTF:

Yes you need to add ldc2 to your PATH. So if your ldc2 binary is in
/user/something/something/folder_where_is_ldc2/ldc2
you havto add /user/something/something/folder_where_is_ldc2 to your PATH.
You can test this by pasting this to terminal:

yes, for classes you can use scoped:
import std.stdio;
import std.typecons : scoped;
class A
{
void saySomething()
{
writeln("Hi from A");
}
~this()
{
writeln("Destruct A");
}
}
void main()
{
with(scoped!A())
{
saySomething();
writeln("s

I would say it is a still regression, but I agree with you, that it should
not work on the first place.

can you try it with c math functions?
instead of std.math, try to use core.stdc.math

Yes, exactly. Some people even use static if it is not needed because it is
harmless. And remove it only when enclosing context is demand.
