Actually... let's not even worry about the definition of the word 
'pure'. Let's just ask ourselves: do we really want to live in a 
world where people can write code like that:

void main()
{
     auto x = pow2(3);
     enum y = pow2(3);

     assert(x == y + 3);

     writeln("Take that mr. \"math\" professor!");
     readln();
}
