That's bug city... the dummy argument is better, or a named
static factory function.
Foo foo = Foo;
Foo foo = Foo();
those are different with static opCall. It also conflicts with

That's not really true, you can have an optimized debug build.
dmd's -debug, -g, and -O switches are all independent. -debug
turns on blocks labeled with the `debug` switch in code. -g adds
info for a

there doesnt even need to be a value pushed on the stack (i=0),
what would be like having a constructor with zero arguments (i
is never used!).
This is so, so irrelevant.

Thank you, one last question:
If i declare the parameter as ref i, then there shouldnt be any
overhead wouldnt it?
Thanks :)
That would be basically the exact equivalent - instead of passing
an int, you'll be passing a pointer.

Hey,
yes i did but to be honest i used dmd in debug version.
The thing about the static one, is that it creates a local
object A isnt that a performance issue itself - or am i wrong -
im confused actually :P?

Hey there:)
i want to know whether the following is somehow possible:
structs dont have default constructors, i know so:
struct A
{
int field;
this(int i){field = getDataFromFile("file.txt");}
}
A instance = A(0);
