Sorry. The previous is not the one causes the problem.
Try this:
struct S {
string str = Hello; // Adding an initial value here.
};
S g_s;
unittest {
S s1;
S s2;
assert(s1 == s2); // Success
assert(g_s == s1); // Fail
auto s3 = g_s;
assert(s3 == g_s);; // Even this

Thanks. Removing the ';' after struct and class is really helpful. The
; keeps trapping me in C++ coding. :)
The following expression compiles but does not make sense.
string str = hello ~ 10;
assert(str == hello\n);
Is this a useful feature or just a bug?

int and dchar implicitly convert to one another for better or for worse.

I'd call it trash-feature :-|

I believe that the primary reasoning for allowing the implicit conversion
between int and dchar is so that code like this
dchar c = 'a' + 7;
That's a '+' though, not a '~'.
I think it shouldn't be allowed with ~ since it's misleading.
Newbies would probably expect abc ~ 10 to yield abc10

Do you like the idea of a POD that is always managed by reference, as

Yes, the docs don't elaborate or include an example. So, for posterity's
sake here's a quick example:
import std.stdio,
std.signals;
void main()
{
auto foo = new Foo;
auto listener = new Listener;
Dear Friends,
Here is the QUESTION:
Does anyone know of any good books that talk about how computers work
abstractly enough to be a solid cross language foundation?
To put this question another way, I REALLY want to actually understand The D
Programming Language by Andrei Alexandrescu. I
Here's a classic:
http://en.wikipedia.org/wiki/Structure_and_Interpretation_of_Computer_Programs
A video series by the authors (from the 80s I believe) was recently made
freely available and I found it really fascinating though I was already
familiar with the content. Highly recommended:
I've started in java with the book java for students at the age of 13, it
was a very well-written book and easy to understand so I bought another book
from that author vb.net for students. fascinated by one of the last
chapters which went 'under the hood' I searched some more about compilation
and
One really good book I read ages ago that takes the magic away from c++
and talks about how it's translated into an underlying implementation is
Inside the C++ Object Model by Stanley Lippman. While it's written with
c++ in mind, it's details can be abstracted to just about any object

There is no Beginning D or D For Dummies yet.
There is a Turkish D book that targets programming novices:
Johannes Pfau made an updated version of std.signals, I think he's
hosting it somewhere on his dropbox, you'll have to ask him.
This code, that a sane language/language implementation refuses at
compile-time, runs:
import std.stdio;
void main() {
writefln(%d, hello);
}
And it outputs:
['h', 'e', 'l', 'l', 'o']
Is this good/expected/acceptable/buggy?
Bye,
bearophile
That's a sweet trick right there. I get different results but I guess
this is due to new std.format changes:
[104, 101, 108, 108, 111]
Did D2 ever implement the Eiffel old construct? I do not see it
mentioned in The D Programming Language, and the only reference I can
find in the newsgroup is a short discussion in June of 2007 that seemed
to go nowhere.
If not, has anyone developed a reasonable workaround? Thanks.
