There was long discussion here. Maybe you did not read.

void slowbad(delegate void() f)
{
    f();
}

void fastgood(alias f)()
{
    f();
}

void main() 
{
    void f() { }
    slowbad(&f);
    fastgood!(f);
}

Syntax is different but power is very different. std.algorithm uses alias always. Everybody else uses slowbad ^_^ Dee Girl
