const argument

[TSalm]

Hello,

Is there a way to specifie a constant argument ( I would say an argument  
for which his value is evaluate at compile time )

For example, something like this :

/* -------- CODE --------- */
import tango.io.Stdout;

void func(const bool constArg)
{
    static if (constArg)
        Stdout("Yes").newline;
    else
        Stdout("No").newline;
}

void main()
{
    func( true );
    func( false );
}
/* -------- END CODE --------- */

Thanks in advance,
TSalm
