The constraint that fails is the one with `CommonType`:

`CommonType` uses the `?:` operator to derive the common type:

No, but because

It's not a bug. The `@attribute:` syntax applies to all following
declarations _inside the current scope_, i.e. until your mixin
templates closing `}`.
Here's what I suggest:
alias T = int;
class VariableLengthClass {
private:
string someMember;
size_t length_;
T[0] data_;
public:
static make(Args...)(size_t length, Args args) {
