I'm a little confused about argument dependent lookup. Exactly when does
this apply? Specifically, I was hoping to use it to access enumeration
constants. For example:
namespace Flags {
enum flag_type {F1, F2, F3};
}
void foo(Flags::flag_type f)

I'm trying to compile the following code with gcc (version below). I
would expect the compile to try the operator ==() declared in
Tangram::Backend because of Koenig lookup. But it doesn't happen. Is
it me or the compiler?

namespace Backend {

I've been reading about how evil Lookup fields in tables are, but I've got
to be missing something really basic. I know this subject has been covered
before, because I've just spent an hour or two reading about it on google,
but there is something I still don't understand, and I'm hoping someone will
be willing to explain it to me in small...

I have a database with four table. In one of the tables, I use about
five lookup fields to get populate their dropdown list. I have read
that lookup fields are really bad and may cause problems that are hard
to find. The main problem I am having right now is that I have a report
that is sorted by one of these lookup fields and it only displays...

Hi,
I want to distinguish between an int parameter to a template function

The so-called koenig lookup allows doing odd things like this:
#include <algorithm>
#include <string>
int main()
{
std::string table;
sort(table, table+10);
}

Hi,
I'm wondering if Koenig lookup can be applied somehow to derive which
template to use based on the template arguments.
The following code shows an example where multiply_traits's namespace
A has to be specified in the definition of Y. This makes Y unusable
for any multiply_traits defined in other namespaces, which

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it. ...
