I don't think so, but you can do something like this with templates:
void swap(alias a, alias b)() {
auto t = a;
a = b;
b = t;
}
int a = 1, b = 2;
swap!(a, b);
assert(a == 2);
assert(b == 1);
2) D doesn't seem to support the list comprehension syntax available in
python and javascript. Is this correct?
[f(x) for x in list if condition]
Don't think so. You can use std.algorithm, but it's a bit harder to read:
auto arr = [1,2,3,4,5,6];
auto res = array(pipe!(filter!"a>3", map!"a*2")(arr));
assert(res == [8,10,12]);
// or
auto res2 = array(map!"a*2"(filter!"a>3"(arr)));
assert(res2 == [8,10,12]);
But I'm a newbie myself.
