Speaking only for lighttpd, it didn't work too well for me when I tried

Hey guys,
I've got a problem - I've just written a few lines to approximate PI with the
Monte Carlo Method.
This is my code:
import std.stdio, std.conv, std.string, std.random;
void main()
{
string buf;
int n, hits;
float x, y, pi;
Random rnd;
rnd.seed(u
'hits' and 'n' are both integers and hits < n, therefore hits/n = 0
in integer arithmetic.
You need to convert at least one of them to a floating point type,
e.g., with 'cast(double)(hits)/n'.

The problem is that spawn only accepts immutables and i have no idea

This is not related to your question. I just wanted to point out that it
is better to use the normal increment operator in the majority of cases.
(I avoid calling it pre-increment, because that name suggests a more
complicated semantics than there actually is.)

Hey guys.
I just want to write a few console applications. Usualy I have to read numbers
to calculate some values. But what's the smartest way to read and convert the
input?
I've coded these lines:
import std.stdio, std.string, std.conv;
T readNumber(T)()
{
string buffer;
stdin.
import std.stdio;
T readNumber(T)()
{
T result;
stdin.readf("%s", &result);
return result;
}
Throws a ConvException if the input string wasn't in the right format.

The HTML docs explain how to use it. Not mine, but I think this would
be a sweet addition to Phobos imo.
Thanks a lot. That's exactly what I was searching for.

I don't get the exception on Linux after a new line, I have to wait
until EOF, which is typically the end of the program if reading from
STDIN. Not very useful.

Yes, you are right. You can make it work by changing to line buffering:
stdin.setvbuf(null, _IOLBF);
But at that point, another solution (like using std.conv.to) is
probably the better choice.

++i is unidiomatic, and if the result is unused it means the same thing
as i++. So, I'd actually go with i++. The only reason why one would use
++i is because it is less efficient for C++ iterators, but D does not

size_t can easily bite you* in the ass:

That one is easy to catch, but in a complex expression you might have

The semantics of cast() was never formalized, I think. People use this idiom,
so I think we have to formalize what cast() exactly does. This is meat for
Bugzilla or even for discussion topic in the main D newsgroup.
Generally
.sizeof on a struct works nicely since it's a POD, but this can't work
on classes since it just returns the pointer size.
I don't know whether this is useful all that much, but I'm curious how
