Reply to Andrei,
I've repeatedly failed to figure out the coolness of C#, and would
appreciate a few pointers. Or references. Or delegates :o).
The coolness of c# is that (in order, IMHO) 1) the tools are world
class, 2) the support is back by MS, 3) the docs are great, and 4)
the language is highly consistent and conservative, e.i. nothing is
added until they've got it right.
Aside from #4, the *language* isn't anything to write home about.
Have you seen Linq? That's *amazing*!
LINQ is the only thing c# has the is a notable language feature, but I don't
think it adds anything that puts it much above the rest of the crowd in any
way.
You can deal with expression ASTs and do really cool stuff with that.
Like doing:
var results = someObjectsThatAreGoingToBeTakenFromTheDb.Where(o =>
o.Name == "Foo");
I think this will work:
int delegate(int delegate(ref T)) Where(T[] array, bool delegate(T) dg)
{
struct Ret
{
T[] Array;
bool delegate(T) Dg;
int opApply(int delegate(ref T) idg)
{
foreach(ref T t; Array)
if(Dg(t)) if(int ret = idg) return ret;
return ret;
}
return &(Ret(array,dg)).opApply;
}
}
If not, a little tweeking shloudl cover it.
There is a lib I played around with a whole back that showed that D can do
AST manipulation with expressions.
foreach(var result in results) {
// There, the previous condition with the given expression has been
// translated to SQL and executed.
}
I find C# a really nice language.
I do to, but mostly because of the tools
