This should be a tribool-like type.

The good thing regarding the run-time overflow integral tests is that
they are already implemented and

Bearophile, haven't you ever read that paper on integer
overflow, which you keep posting to the newsgroup???
I have read it time ago, but it seems not having run-time
overflow tests is not an option for certain programming endeavors
of mine. This is why I have partially

Currently in D you can only overload struct and class operators.

Hello everybody!
I am new to D, and I am working on a program that calculates the
area and circumference of a circle. However, when I compile it
and run it, it waits for the user to input the radius, but then
it closes while displaying a bunch of stuff.
I've tried several ways to get it to
By the way, this is just my 2nd program in D.
It is just for fun, and I'm doing it to practice using this

This is normally how I teach myself languages.
I write a simple one then a more complex one on and on until I'm
fluent in the language.

You should be able to just do a readln() before exiting
to give the user a chance to read everything, and hit
enter to exit.

I just tried that, and it still closed right after I typed the
radius.
It looks almost like error code

Normally, the rdmd tool will compile and immediately execute
the jeteste program. Rdmd is smarter than dmd, because it
will calculate all the files that you need
I'll probably put in this alternative:
void wait()
{
char[] a;
while(a != A)
{
writeln(Type A to continue!);
stdin.readln(a);

Thanks!
So, I've taken out the loop part that is interesting and
replaced it with the readln() alternative.
However, I'm still getting what looks like an error.

Similar things happen often. But Andrei says this is good,
because it's more orthogonal. As Sting, I don't subscribe to this
point of view. Orthogonality isn't more important than

That must be why, I didn't import std.string!

I agree with Andrei, there is no outlet for errors in the to!T
function, exception is the logical choice.
Maybe I was not clear enough, so let me explain a bit better.
What I don't like is to!int(15\n) to be seen as an error in the
first place.
I'd like it to ignore
