I tried Descent, but it didn't work well at all with my D2 program. It
also didn't support building. I'll look into Poseidon. Thanks.
D2 support isn't that good in Descent yet.
Exactly. I think the parser is ported up to 2.030 but I didn't test it a
lot

You must have two different HANDLEs around.
The one in phobos is aliased to void* and there is no LoadLibraryEx call

Try using the FQN of the import where you are getting the LoadLibraryEx
from.
Thanks for your help.
Hi,
I'm trying to fetch a module's dependencies with the deps switch, but it
gives me an empty list.
dmd main.d -deps=foo.txt
foo.txt is empty.
main.d is:

module main;
import other;
int main(char[][] args) {
someVariable = 3;

If you want the result to be again7hello, then no. You must do:
char[6] t = ragain ~ '7' ~ rhello;
or:
char[6] t = ragain ~ (cast(char)('0' + 7)) ~ rhello;

But you never inserted anything in aa[test].
You must do:

aa[test] = s;
aa[test].i = 10;
or:

Descent has a compile time view that is supposed to do some of this.
If you are only looking at string mixins you can use pragma(msg, string)

Many people (even Brian Kernighan?) have said that the worst feature
of C is that switches don't break automatically before each case
label.
Oh god, that's from 1984, and even today

What kind of fall-throughs were these?
A:

The solution is to forbid fallthrough, and change the switch syntax:

Your idea was to give an error on the case (B) he uses. Or did I miss
something?
You missed the alternative syntax to get the same behaviour. But it's a
very subtle difference.

Do you mean the multiple cases?

Yes, but make the multiple cases the *only* way to make case
statements fallthrough.

That is the same as giving an error on case B, right?
Well, yes, but you also have to prepare your mind for the change. This
is a huge step.
