Hello everyone,
I am playing around with DSFML and drawing some stuff on the
screen. It works like a charm but I got some unexpected behavior
when building a `Particle` class.
My class looks like this:
```d
class Particle : Drawable
{
CircleShape shape = new CircleShape(5);

This `new` is actually run at compile time, so every instance of
Particle refers to the same instance of CircleShape (unless you
rebind it).

The compiler did not complained, and it was OK for him.
```
c++ -c MyClass.cpp
ldc2 main.d MyClass.o -L-lstdc++
```
```
extern(C++){
class MyClass {
public:
int num=1;

PS: I managed to link to phobo's/runtime & wxgtk at the same time.
It goes like this [So someone does not need to re-invent the weel]

I'd recommend you to use templates with alias parameters but you
mentioned that you need to retain function context(for gotos,
continue, break, etc...)
One thing you could do is mix the ugly mixin solution with the
good one:
```D

Crystal is Web-only focused.
And Crystal is not popular, even compared to D.
