The subject says it all really. i have this example:

int value=5;
public int getvalue(){
return value;

int main(string[] args) {
GC.disable;
static fruit myfruit;
return myfruit.getvalue();
}
Most of the smart people will see that i want the program to return 5
but I did something dumb and didn't put in the "new" statement?
So my question is in longer words "Can I create instances of objects at
compile time?" and if not "why not, i could build something
(roughly)equivalent out of structs and functions and have it at compile
time?"
Rules about CTFE, I have:
1. It must be valid D code
2. Source code must be available during compilation
3. If its not passed to a function, its not available
4. You don't care about performance
5. Templates are your friend
I prefer to add pure to any function I intend to be CTFE'd.
So yes you can use new for classes at CTFE, just don't expect it to be
collected and finalized.
