Currently this works, and ct_function() is run at compile-time because fixed
array length definitions is a compile-time context, so in D it forces CTFE:


int ct_function(int x) {
    return x * 2;
}
void main() {
    int[ct_function(5)] a;
}


If VLA come in D, and if their definition syntax is the same as the current
fixed array definition syntax, then that length definition stops being a
compile-time context, and the compiler is not forced (but free any way) to run
ct_function() at compile-time.
