1. In C and C++, you have to define the size of the array. In D, 
you can just leave the brackets empty.
2. You can return an array directly. In C and C++, you would have 
to return a pointer to an array:

int* return_int_array() {
int* ret = new int[3];
return ret;
}
3.The foreach loop. Just iterates over things. You could also use 
a for loop in place of this, but writing out a foreach loop is 
shorter and is easier to read.

4.  Mixins. These allow mixing in strings into the code. These 
are not in C or C++.

Completely unrelated, but is this code valid?

import std.string;
import std.stdio;
T someTemplate(T) () {
//function template
}

void main(){
string template_type;
strip(readln(data));
mixin("someTemplate!" ~ data ~ "()");
}
