#13807 — struct error

I'm experimenting with using a struct within a vector located in a
different struct. I'm getting a compiler error. Here are the
structures:

struct shelf_item
{
    std::string name;
    int weight;
};

struct shelf
{
    std::string location;

    // compiler error occurs here
    std::vector<shelf_item>;
};

The compiler error reads: "a template-id may not appear in a using-
declaration"

Standard types (string, int, etc.) work fine, but my struct doesn't.
There's likely a better way to approach this, but having never tried
it before I wanted to ask here. Not sure it matters, but I'm using g++
4.6.2.

Thanks for any advice.

It's late and I made a typo... I figured it out:

std::vector<shelf_item> si;

Sorry for the noise.

#13809

Copying any object stored as a tree like data structures of more than two digit 
levels is really slow for the spread blocks in the heap space.


Anyway DRAM is getting cheap so fast, thus the operator reloading is getting 
cheaper more and more in the 16 to 64 giga heap sace and the tera bytes 
in the HD.
