The following code will cause a error: 
Error: cannot implicitly convert expression ([2,3,4]) of type int[3] to ubyte


ubyte a[3] = [2, 3 ,4];

That worked for me.

Windows XP SP2, DMD 1.007

-----------------

c:\temp>type test.d
ubyte a[3] = [2, 3 ,4];
void main(){}
c:\temp>dmd test.d
c:\dmd\bin\..\..\dm\bin\link.exe test,,,user32+kernel32/noi;

c:\temp>dmd
Digital Mars D Compiler v1.007

}

That's not static initialization.  It needs to be at the module level 
for that, or be declared as 'static ubyte a[3]'.

I think maybe he's just getting terms mixed up.

In any case, to be able to do this in a function, you have to write

ubyte[3] a = [cast(ubyte)1, 2, 3];

The compiler isn't smart enough to figure out that maybe, just maybe, that 
array literal should be a ubyte[] instead of an int[].  :P

As I've begun to say before, array literals ought to be multi-typed in much the
same way as string literals are.

But even so, it should be possible to make the compiler treat it as an
initializer rather than an array literal; then there would be no problem.

This was still failing in DMD1.020, but was fixed by 1.041.
