int* p;
int[] a=[1,2,3];
p=a;

spec says it should compile, but it won't. Where is the bug - in spec or in
compiler.

In the spec, the implicit convertions to .ptr property was removed some 
time ago.

p=a.ptr;

If I had to guess, I'd say the spec is wrong. It's a narrowing
conversion. Data is lost. To mind, that means it ought to require an
explicit cast.

Hmm... It's ref types, they are casted differently.

You must be looking at a terribly out-of-date spec.

See the "Implicit conversions" section.  As was mentioned, implicit 
conversion from T[] to T* was removed more than a year ago.

this section is for objects - reference types, I'm talking about value types.
Look at sections Usage and Strings.

int* p;
int[3] s;
int[] a;
p = s;		// p points to the first element of the array s.
p = a;		// p points to the first element of the array a.

char[] str;
char* p = str;		// pointer to 1st element

Of course array of ref types can't be converted to pointer to this ref type
because D doesn't support pointers to ref types.

oops, my bad.
