This is infinite loop:
for (ubyte i=0; i<=255; i++)
{
...
}
I guess it's a bug?
A ubyte is ALWAYS <=255, since ubyte 255 + 1 == 0.

One way to scan all the ubytes with a for loop:
import std.stdio;
void main() {
for (ubyte i = 0; ; i++) {
write(i, " ");
if (i == 255)
break;
}
}

So the struct is defined as:
struct S(T) {
}
template isS(T) {
// ...
}
static assert(isS(S!float));
static assert(!isS(float));
There may be some nasty ways using fullQualifiedName!T and so on
but I guess there is a better way, isn't it?

Isn't both "i" and "255" should be propagated to
int before comparison?

Implicitly propagated, I mean.

Implicitly propagated, I mean.
Regardless, a ubyte 0 converted to an int is still 0.
a ubyte can only hold a maximum of 255 and will roll over to 0

You mean like this?
void main() {
ubyte i = 0;
do {
write(i, " ");
} while(i++ != 255);
}
or
void main() {
ubyte i = 0;
while(true) {
write(i, " ");
bioinfornatics:

It uses less lines of code, and with the for loop you have a
single place where to put the loop variable initialization, test
and increment. This makes the code simpler to read. In this case
the test is moved inside the loop, but it's

The reason is the print method is private, which means it is also
automatically final and doesn't access any member variables.
Since it doesn't access members, it doesn't actually try to

You don't actually dereference ›this‹ in print(), so the null
value in the implicit this parameter doesn't matter.

That's fine. There is no check for null at every possible occasion, like I
think in Java. The operating system will catch any actual null dereference
though,

There is no compiler bug. You cannot pass immutable/rvalue by reference
to mutable.
I'm trying to write a Cross and Dot function using
core.simd.float4 and DMD
The C++ code looks like:
from:
http://fastcpp.blogspot.com/2011/04/vector-cross-product-using-sse-code.html
inline __m128 CrossProduct(__m128 a, __m128 b)
{
return _mm_sub_ps (
_mm_mul_ps (
_mm_
On a side note, if I run the simple code:
void16 a = 0, b = 0;
void16 r = __simd(XMM.PSHUFB, a, b);
writeln(r.array);
I get the following error:
Internal error: e2ir.c 3817

Does anyone know anything about SIMD operations that may be able to help
me translate these functions into a D equivalent? I would very much
appreciate your help.
