I think append() could be a part of std.array but I can't find
anything like that in Phobos.
Nothing new here... I'm just reminded of how templates can help with DRY
(don't repeat yourself) code.
Here is a piece of code that uses an alias to be flexible on the element
type:
import std.conv;
alias MyType = double;// <-- Nice, MyType is used twice below

You need to read about templates in D, here's a good guide:

void baa() {

void main() {
