Are all your benchmarks done on a 64 bit system?
They are. Here's one comparison with 32 bit (for complex single
precision transform using sse)if you are interested in that:

because there are less general purpose and SSE register

I think what Phobos does in
this case is wrong. The fact that one class works on all
floating point types results in very poor precision when
the data consists of doubles or reals. I guess that precomputed
tables are stored as floats. You

Everything looks nice. Are you using "in",

Not yet, but I plan to add those.
Is it worth changing the Phobos API to something

Is it worth changing the Phobos API to something similar to this
API?

Personally I think this is heading in the wrong direction. A D user
shouldn't have to deal with C

Can I ask you something? Do you know if (lib)clang exports typeinfo
for default values? For example:
namespace Foo
{
enum En
{
Val1,
Val2
};
}
void test(int x = Foo

'x' has typeinfo

'x' has typeinfo (it's an int), but I'
10 matches
