D is statically typed, so it's better to refuse it at compile-time.

Actually, it would be very cool if D would re-use the integer range trick here and catch all cases that can be proven not to work using it, such that the following code would error at compile time: ;)

int x;
readf("%d",&x);
real[2] foo =
    x%100>50 ?
    [1.0L, 2.0L, 3.0L][0..2|x&1] :
    ([1.0L, 2.0L] ~ [3.0L, 4.0L] ~ 5.0L)[x&1..$-!(x&1)];

Yes, but that's bug 2547.
