Remove incorrect statement on array passing.

[bhelyer]

This confuses people that don't understand that arrays are passed by value, even though they contain a reference.

It would be nice to have this article on slices linked in the Articles section, so instances like this can be replaced with a link.

@schveiguy, you wrote this, if I'm not mistaken? What do you think?

I think the whole memory article applies only to D1/phobos1, and is quite out of date. However, in that context, I would suggest saying "since the contents of the array are passed by reference".

I have committed in the past to adding my array article to the actual ddoc site in the section on articles. I just haven't done it yet (need to port all the TRAC wiki stuff to ddoc).

I have another pull request (#45) which aims to bring it up to date with D2 and Phobos2. It doesn't fix all of it, but I aim to convert more of it in the future.

The purpose of the memory article itself has not been obsoleted, the fundamentals remain the same as before: D primarily uses GC for classes, but supports modeling your own allocation strategies, which the article exists to explain.
