I don't understand what's happening here, but there is a problem somewhere
(maybe in this code), D2 code:


import std.stdio, std.typetuple;

alias TypeTuple!((double x){ return x + x; },
                 (double x){ return x * x; }) funcs1;

double foo1(double x) { return x + x; }
double foo2(double x) { return x * x; }
alias TypeTuple!(foo1, foo2) funcs2;

void main() {
    enum double x = 5.0;

    foreach (f; funcs1)
        writeln(f(x));

    foreach (f; funcs2)
        writeln(f(x));
}


It prints (DMD 2.052):
5.28268e-308
0
10
25

Instead of:
10
25
10
25
