template a(alias b)
{
    alias T = typeof(b);

    auto a(T ret)
    {
        return ret;
    }
}

auto a(T, size_t N)(T[N] a) {}  // breaks
// auto a(T)(T[] a) {} // OK

void main()
{
    int x;
    auto b = a!(x);
}

test.d(5): Error: undefined identifier 'T'
test.d(16): Error: cannot infer type from template instance a!(x)
