Hi,everyone,
How to test that the IP port is reachable?
In C,you can do this like that, what should I do in D?

It looks like the compiler is treating that as a function
prototype without a body (that just happens to be nested in
another function).
return foo;
And then, this foo is given the optio
module mymodule;
class Foo{}
Foo Bar()
{
Foo foo();
return foo;
}
int main()
{
auto foo = Bar();
return 0;

This code doesn't compile with a linker error that there's a
missing symbol for `Foo Bar()` on windows.
After all, `Foo foo();` isn't legitimate

Hello,
Since literal strings are interned (and immutable), can I count on the fact that
they are compared (==) by pointer?
Context: The use case is a custom lexer for a custom language. I initially
wanted to represent lexeme classes by a big enum 'LexClass'. However, this makes

BTW `T.stringof` is usually a bug waiting to happen. You are
using mixin in a lot of places where you shouldn't be and this is
going to lead to name conflicts, import problems, and more. Just
use `T`.
If you need a member, use __traits(getMember, T, "name").

Your code has a lot of layers to unfold, but instead let me just
show you a working example and then maybe you can fix your own
code:
---
class A {
void foo(int a) {}
void foo(int b, int c) {}

You are just having a little issue with operator precedence
there. Your code attempts to get the member `A` from
`MyClass!MyEnum`, if you add braces around it, it'll work just
fine `MyClass!(MyEnum.A)`.
That's really funny acutal
