Yeah, D feels like that to me too, sometimes. Anyways, for your question -
would using the struct name be good enough? They're easy to get hold of
and usable in switch statements.
If not, how about this:
import std.typetuple;
struct TypeEnum( T... ) {
static pure nothrow @property
Hello!
I have some structs
struct A { int a; }
struct B { int b, c; }
and I'd like to be able to enumerate them (preferrably as integers) based on
their names. I've no idea how this would look, but
some pseudo code that would use this feature:
// pseudo
int type = stream.read!int();

Still, is the multi-dimensional part possible?
Sure, you have to make an opApply that takes several parameters in its
delegate.
An exemple:
struct TwoDArray(int nx, int ny)
{
int[nx][ny] data;
int opApply(int delegate(ref int i, ref int j, ref int cell)

Interesting!
I get the same result, ie an infinite loop, with the CPU at 100%
Some things I noticed:
- Changing the for-loops to 100 or 10 doesn't help.
- Changing the atomicOp from += to just + makes it work (although the
account doesn't get changed)
- Adding a Thread.sleep(1000) in one of the
Hello!
I've been trying to strip an executable created with DMD from symbols. Has
anyone any experience with this?
I can't seem to rid my execs of more or less containing the entire class-tree.
Example:
// sym.d - - - -
import std.stdio;
class Bunny{
int x;
int getX()
? Seems the OSX-strip is acting funny? Or
could it have something to do with DMD still? Maybe I should ask in some
darwin-forum about strip...

I don't really like it. Of course the order of indices feels better but
it breaks the rule of reading types from right to left. It also

Ops is a type, isn't it? Don't you need a variable there?
