Re: dmd 1.047 and 2.032 releases

Indeed, using CTFE will probably feel different after this release of D1/D2. 
Good work.

I'd like to improve this Wikipedia page some more:
http://en.wikipedia.org/wiki/Compile_time_function_execution

So after all such bugfixes are there better ways to implement the following 
code (better = simpler, more natural, etc)?

import std.stdio: writeln;

int[] genFactorials(int n) {
    int factorial(uint n) {
        int result = 1;
        for (int i = 1; i < n+1; i++)
            result *= i;
        return result;
    }

    int[] result;
    for (; n >= 0; --n)
        result = factorial(n) ~ result;
    return result;
}

const int N = 13;
static const auto factorials = cast(int[N])genFactorials(N - 1);

void main() {
    writeln(factorials);
}

For me creating tables at compile-time is an important use case for CTFE. But 
that CTFE code is/was fragile, if you change it a bit it stops compiling.
