D - Cast syntax

I just noticed that the C-style cast syntax has been deprecated (was trying to
compile DUI when I discovered it.)

One question though... what is the merit in replacing one hard to read cast
syntax with another, equally hard to read and on top of all unfamiliar, syntax?
That is, what does this:

cast(char *)(p + 2)

Do for me over this:

(char *) (p + 2)

?

In my opinion, a cast method is fine, but it would be far simpler to read and
write if it looked like this instead:

cast(char *, p + 2)

I'm not sure why it wasn't done this way or even if it's feasible to do it that
way, but I'm also not sure why you wouldn't fix the syntax properly if you're
going to change it at all. :-)

(I apologise if this has been brought up before but I didn't see the word 'cast'
anywhere in the message listings so I thought it might be safe to bring up.)

Parsing is easier.

That's understable, yes. But if you see this:

cast(a,b);

How do you know if it's b->a or a->b?

Well... I guess...

The same way that you know which one it is when you write cast()()! TX

You're posting on the wrong newsgroup. This one's been retired.

But the answer is that you can grep for cast with ease. It's pretty hard to grep
for casts in and amongst all the other braces.
