Try (walkLength is from std.range):
mydList[].walkLength

So the doubly linked list doesn't know it's length? That seems a bit
inefficient...

Have you tried to compile mydList.length or mydList[].length? If
both don't compile, then you have to walk the items.
Walking the items is not efficient, but:
- Linked lists are very uncommo

There's http://dlang.org/phobos/std_traits.html#hasIndirections

The following seems redundant because the other isFloatingPoint!E

auto ref randInPlace(E)
@nogc
void main(string[] args)
{
immutable(char)[] s1 = "hello";
immutable(int)[] a1 = [1, 2];
}
Why does the s1 not throw an error, but the a1 does? As far as I
can tell, they're both immutable arrays.
Error is: "Error: array literal @nogc function main may cause GC
allocation"

Unrelated to your question, you want to return just Velocity there.
Unlike C++, classes are reference types in D. So, Velocity itself is
essentially a Velocit

Taking a step back, a D program prints to stdout, not console. However,
in most cases a D program's output ends up on the console when it is
started in a console.
So, one can print any byte value to t
