You can name the files the same as their classes:

What namespace? D has modules, unlike C++. In general it's a
bad idea to have inside a module a name (like a variable name
or struct name) equal to the module name, because it causes
confusion.
I am confused as well.

Thanks for the reply, I wasn't familiar with scoped. I was aware
that structs are on the stack and classes are on the heap in D,
but I didn't know it was possible to put a class on the stack.
Might be interesting to see how this is implemented.

The only difference is changes to length won't be seen outside

Hello. How can I call a function with null as parameter, which I

I can't call this function like:
