AppendStructuredBuffer<float4>  append_buffer;
ConsumeStructuredBuffer<float4> consume_buffer;
RWStructuredBuffer<float4>      rw_struct_buffer;
RWStructuredBuffer<float4>      rw_struct_buffer_no_counter;
StructuredBuffer<float4>        struct_buffer;

float4 main(uint pos : FOO) : SV_Target0
{
    rw_struct_buffer_no_counter[10] = float4(1.0, 2.0, 3.0, 4.0);

    rw_struct_buffer[7];
    uint c1 = rw_struct_buffer.IncrementCounter();

    append_buffer.Append(float4(1,2,3,4));

    return consume_buffer.Consume() + struct_buffer.Load(20);
}

Problem:
It's not possible to distinguish between these four buffer types via reflection.
They are all backed by the same SSBO type, so changing the type probably won't work.
The name alone has no distinguishing feature which we can reliably extract to figure out which of these HLSL buffer types are used.

One approach probably is to to add @struct, @append, @consume to the OpName of the variable itself.
