I've got a problem with your SecuritiesBasketType protocol and its extension. The problem is best highlighted by taking a look at the multiple classes you've implemented to conform to this protocol.

var name : String = ""

After writing this answer, I was inspired to try to design a more elegant solution to the problem of printing binary trees. And what better tool with which to seek elegance than Clojure?
The solution I ended up with involved creating, merging, and printing what I'm going to call sparse strings. ...
Using Boost.Spirit I decide, that using BOOST_FUSION_ADAPT_STRUCT is shomewhat redundant. It can be avoided using of deducing of result type in conversion operator:

template< typename Iterator, typename Sentinel = Iterator >

I am fairly new to Python but I have been improving, and I wanted to try writing a simple program that simulates locker with multiple chambers(4) for storing "objects".
I recently used lockers at a theme park with a similar functionality.
A chamber can be reserved by simply typing a unique PIN.
