Hi,
You should have a look at the decorator design pattern, it
reduces the amount of classes to implement if you need to combine
different effects such as elemental damage to your weapons (e.g.
if you want flame arrows).
https://en.wikipedia.org/wiki/Decorator_pattern
For my tactical role-playing game, I want to finally implement
items and weapons. These are objects that a `Unit` object can
make use of. Just as tools are often said to be an extension of
their user, I want items to be an extension of the unit who uses
them. I'm trying to figure out how to

Of course you may also combine the up(+) and down(-) step to
one:
1/i - 1/(i+2) = 2/(i*(i+2))

Hello all,
I have two scripts. I copied the first directly from the alpaca
website and massaged it with etc.c.curl until it compiled in D.
The result is that it creates the order and returns the result to
stdout. In the second script, I tried to use std.net.curl but
cannot get it to work.

How to fix it? than you ;)
Try the following:
```

StreamSocketFD client;
ubyte[1024] buf = void;
// Add these two lines
Unfortunately there's no "edit" option here, but the library I
was referring to is actually "libdparse".

Not really..
The speed of Leibniz algo is mostly the same. You can check the
code in this benchmark for example:

I think a few things can be going on, but one way to go is trying
using optimization flags like "-O2", and run again.
But anyway, looking through Assembly generated:
