flexible array members support

[yrashk]

For this data structure:

struct some_person {
    std::string name;
    unsigned birth_year;
    int data[];
};

I am getting this error:

error: type 'some_person' decomposes into 3 elements, but only 2 names were provided

Normal array members work fine.

Do you think it would be possible to support these?

Same applies to zero-sized arrays.

[yrashk]

As far as I can tell, it is failing because for zero-sized arrays the requires in the arity calculator is failing because of initializer for aggregate with no elements requires explicit braces and for flexible members array it fails because of initialization of flexible array member is not allowed

In both cases, a simple array initializer {} works.

Good point, I'll try to find a workaround next time I'm messing with this library :)
