           Summary: CTFE doesn't default initialise arrays of structs

Seems as though struct arrays aren't default initialised inside CTFE.
CTFE disallows concatenation to an unitialised struct array, also can't get the
length.
Workaround is easy - just initialise the array to [].

-----------
struct S {
    int a;
}

int func()
{
/* This is OK
    int [] q;
    q ~=4;
*/
    S [] s; // makes the next lines fail. (but  S[] s = []; compiles).    
    s ~= S(7); // fails
    return s.length; // this fails too
}

void main()
{
    const int x = func();
}
