In D, tuple is not built in type, it
In the C standard library there are the sqrtf, cosf, sinf functions, that
return a 32 bit float. In D std.math.sqrt returns a float if the input argument
is float, but sin and cos return double even if their argument is float:
import std.math: sqrt, sin, cos;
void main() {
float x = 1.0f;

Currently in D there are two ways to return multiple values fro
I have function which have more than one return, and the code compile and run
but it gives rong result -I guess-, so i use tuple but the compiler can't
return tuple.
how can I return values?
why I can't return tuple?

Good.

switch has stronger requirements than a series of if statements and its uses
such extra information to create assembly code that's more efficient than a
series of i

Got it. Bug is reported.
Btw, is there a specific reason why non-const values are not allowed?
I mean, doesn't a switch statement like this:
switch(value)
{
case 1:
foo(); break;
case 2:
bar(); break;
default:
doo();
}
expand to:
if (value == 1)
foo();

I would not know. As long as you do a best guess search on what yo

Yeah that I know.
Do you happen to know if this bug is already filed or should I file it?

Ah, yes, thanks; that looks

Should be: "If your are talking about D2, then use std.algorithm sort
