[Issue 4231] Solitary opUnary Postincrement and Postdecrement user defined operators are broken.
http://d.puremagic.com/issues/show_bug.cgi?id=4231 --- Comment #5 from Andrei Alexandrescu and...@metalanguage.com 2010-06-02 08:57:50 PDT --- That looks like a very specialized optimization to me. In particular, if the postblit has side effects, the optimizer must have advanced knowledge in order to elide it. This is a path that C++ has taken with copy constructor elision, and it's not a path we should take. I think the language definition should clarify that postincrement and postdecrement are lowered into their pre- counterparts if the result is not taken. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

MOST of the time the operators will be inlined and at that point it should be dead simple for it to eliminate dead stores and thus the temporaries would just go away, no special knowledge or techniques required. Without inlining, yeah, it can't make assumptions what can occur inside the function calls. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

This D2 program:
import std.stdio: writeln;
void main() {
enum Foo { Zero, One }
Foo f = Foo.One;
writeln(f);
}
With DMD v2.046 prints:
1
But it's better for it to print:
One

This D2 code works with DMD v2.046:
import std.stdio: writeln;
import std.algorithm: array, map;
void main() {
int[] arr = [1, 2, 3];
auto r1 = map!(a * a)(arr);

auto r2 = map!(f)(arr);

But this program:
import std.stdio: writeln;
import std.algorithm: array, map;
void main() {
int[] arr = [1, 2, 3];
auto r3 = map!((x){ return x * x; })(arr);
writeln(array(r3));

too.

[Issue 4265] New: It should be possible to query template parameters with __traits

Summary: It should be possible to query template parameters

Consider you have
struct(T1, T2) Foo {
}
alias Foo!(int, float) X;
You should be able to extract (int, float) from X.
Often it is possible to get the parameters indirectly from members, but there
doesn't seem to be a way to do this in the general case.
I suggest:
__traits(getTemplateParameters, X)
which would yield a (int, float) tuple.
