In the code below, the variable i is never increased above x+1.  It seems the
declaration inside the loop somehow overwrites i.  (Note that the writeln() is
only for demonstration purposes and has nothing to do with the bug.)


import std.stdio;

void run(fun...)()
{
    fun[0]();
}

void main()
{
    run!(delegate void()
    {
        for (int i = 0; i < 100_000; i++)
        {
            writeln(i);
            auto x = 0;  // i never exceeds 1
        }
    })();
}
