At the present time, SSE and x87 are the same speed in most cases (most
operations take just one cycle) -- except of course that you can do two

Hi, I'm trying to override Object's toString. I've noted it isn't a
const method, namely:
string toString() const;
This cause me troubles when using it on a const reference.
Shouldn't it be const?
Thanks,
Tom;

templates:
void foo(T)(T, void delegate(T) fn)
{
}
This parameterizes foo based on T, which could be A, const A, or int, or
whatever works to compile the function.
What if the parameters are more general, for instance the first parameter is
always a Foo,

Phobos hasn't become very const aware. There have been bugs
When there are multiple calls that can fail, and where I have to do
clean-up code in a certain order and under certain conditions I use
scope(exit). For example:
import std.stdio;
import std.exception;
void main()
{
foo();
}
enum NoError = true;
bool Initialize() { return true; }

So I do believe it should be const, but between the other priorities, and
possible signature change for toString, it isn't done yet.
There also the idea of introducing the writeTo() standard method, that's neat
:-)

Sorry, I should be careful with the word side-effects. What I meant
was the newly spawned thread does its own job that the main thread
doesn't care much about. It doesn't touch main's state or any shared
variables. It does some work other than return a value. But the
function I wanted the new
