In fact, it can nowadays be. You just have to mark it so, with a 
lambda:

void main()
{   import std.stdio;
     auto myArray = [2, 3, 5, 6];
     int k = 2;
     alias a = () => myArray[k];
     writeln(a());
     k = 3;
     writeln(a());
}

//result:
//5
//6

The downside with this (and function pointers and delegates) 
compared to defining functions is that you cannot call it without 
parenthesis.
