Hi,
In Python I can write this:
if (4 <= 5 <= 6):
print ("OK")

In D, I can only write this:
import std.stdio;
void main() {
if (4 <= 5 && 5 <= 6)
puts("OK");
}

Backward compatibility with C is nice but on the other hand it is
a road to nowhere!
Because of this compatibility, I'm compell

What happens in C/C++/D/Java/C#/etc. land is that 4 <= 5
results in a bool,

I would rather write:
if( isSorted![4,5,6])

Something I sometimes do for strictly personal projects:
import std.typecons : ω = tuple;
import std.typetuple : Ω = TypeTuple;
void main()
{
auto a = 1, b = 2;
Ω!(a, b) = ω(b, a);
assert(a==2 && b==1);
}
