Well, not SQL-like exactly. In the C# world, I utilize the Linq extension methods almost exclusively and find that this meets 90% of our needs. So even if that had to appear like Where(my_list, () => { /* a lambda */ }), this would be perfectly fine.
However, putting syntax aside, MultiIndex offers very powerful and
flexible facilities. Sometimes you can also combine it with Lambda or
Phoenix to get some "syntactic sugar", like this:

May be worth looking into, thanks. For now, I'm going with STL/NET for its .NET-friendly map<> since I want to map C++/CLI managed classes into the structure. It's a little more work, but not a lot more work, to get at the keys and/or values for the questions we want to ask. This requirement may out-weigh using boost-collections, etc.
Thanks for the response.
