Strange `tuple used as a type` error if using: template tuple parameter + named
argument of its type + an constraint.
---
void f(int n)(int) { }
void f(U...)(U){ } // ok
void f(U...)(U a) { } // ok
void f(U...)(U) if(true) { } // ok
void f(U...)(U a) if(true) { } // Error: tuple U is used as a type
void main() { f!0(0); }

FWIW, I've found another way to reproduce this bug:
import std.range, std.algorithm;
double fun(double x) { return x; }
void main() {
map!(fun)(indexed([1.0, 2], [0, 1]));
}
Using DMD64 on Linux (This is a 64-bit specific issue, adding -m32 makes it go
away. It also only happens with -release.)
dmd test.d -release

[Issue 4124] toString() for BitArray and more
http://d.puremagic.com/issues/show_bug.cgi?id=4124
--- Comment #1 from bearophile_h...@eml.cc 2011-10-13 11:22:06 PDT ---
Maybe the usefulness of isSet(), set(), and reset() methods is visible with two
benchmarks. They implement the same algorithm (a simple sieve), the first uses
a BitArray, and the second a manually implemented bit array. On my 32 bit
system the second program is about two times faster than the first one.
import std.stdio, std.algorithm, std.range, std.math, std.bitmanip,
std.datetime;
uint[] primes(uint n) {
if (n 2) return [];
BitArray F;
F.length = n + 1;
F[0] = true;
F[1] = true;
foreach (i; 2 .. cast(uint)sqrt(n))
if (!F[i])
for (uint j = i * i; j = n; j += i)
F[j] = true;
return array(filter!((i){ return !F[i]; })(iota(n+1)));
}
void main() {
StopWatch sw;
sw.start();
primes(30_000_000);
sw.stop();
writeln(sw.peek().msecs / 1000.0);
}
import std.stdio, std.algorithm, std.range, std.math, std.datetime;
size_t[] primes(in size_t n) {
enum size_t bpc = size_t.sizeof * 8;
auto F = new size_t[n / bpc + 1];
F[] = size_t.max;
bool isSet(in size_t i) nothrow {
immutable size_t offset = i / bpc;
immutable size_t mask = 1 (i % bpc);
return (F[offset] mask) != 0;
}
void clear(in size_t i) nothrow {
immutable size_t offset = i / bpc;
immutable size_t mask = 1 (i % bpc);
if ((F[offset] mask) != 0)
F[offset] = F[offset] ^ mask;
}
clear(0);
clear(1);
foreach (i; 2 .. cast(size_t)sqrt(n))
if (isSet(i))
for (uint j = i * i; j = n; j += i)
clear(j);
return array(filter!isSet(iota(n + 1)));
}
void main() {
StopWatch sw;
sw.start();
size_t n = primes(30_000_000).length;
sw.stop();
writeln(sw.peek().msecs / 1000.0);
writeln(n primes: , n);
}

Even more thoroughly reduced test case:
void main()
{
auto foo = Indexed([1.0f, 2, 3], [1, 2, 3]);
}
@property ref T front(T)(T[] a)
{
return a[0];
}
struct Indexed
{
float[] _source;
int[] _indices;
@property float front(float newVal)
{
return _source[_indices.front] = newVal;
}
}

[Issue 6812] New: Failed equality of structs with string field
http://d.puremagic.com/issues/show_bug.cgi?id=6812
Summary: Failed equality of structs with string field
Product: D
Version: D2
Platform: x86
OS/Version: Windows
Status: NEW
Keywords: wrong-code
Severity: normal
Priority: P2
Component: DMD

This program produces a runtime assert error, it's a bug:
struct Foo {
string s;
}
void main() {
Foo b1 = Foo(hello.idup);
Foo b2 = Foo(hello.idup);
assert(b1 !is b2); // OK
assert(b1 == b2); // line 8, error
}
With DMD 2.056head it gives:
core.exception.AssertError@test(8): Assertion failure
The equality among structs has to call the string equality of their fields. The
is operator has to compare the structs bitwise.

Class type has same problem.
struct Foo {
string s;
}
struct Bar {
static class X {
bool opEquals(Object o){ return true; }
}
X x;
}
void main() {
Foo f1 = Foo(hello.idup);
Foo f2 = Foo(hello.idup);
assert(f1 !is f2); // OK
assert(f1 == f2); // error
Bar b1 = Bar(new Bar.X());
Bar b2 = Bar(new Bar.X());
assert(b1 !is b2); // OK
assert(b1 == b2); // error!
}
