I'm looking at the D reference manual in the "arrays" section. It says under
"usage":

int* p;
int[3] s;

p = s;		// p points to the first element of the array s.

But when I try this I get:
"cannot implicitly convert expression (s) of type int[3] to int*."

Why? Is the manual wrong or the compiler or what am I missing?

Oh..

Deprecated in what way? Made illegal or obsolete or..?

Can I use an explicit cast? Will it work?

Like this:
p = cast(int*)s;		// p points to the first element of the array s.
?

Made illegal.  There were too many "gotchas" when passing arrays to C 
functions (which is really the only time this conversion was used).

You can just use the .ptr property of the array:

char* p = s.ptr;

Effectively, obsolete but not yet illegal.  Code that uses deprecated features
can still be compiled using the -d compiler option.

 Like this:
 p = cast(int*)s;	// p points to the first element of the array s.
 ?

You could, but perhaps nicer is to just use the .ptr property.

The best way I can find is to:
p = &s[0];

Or as others have said, just use the .ptr property.
