It is not really a container in the sense that I add and remove 
items at random later in the program. The items are added in a 
loop after initialization (say every single letter of a word). 
Since it happens very often and there can be loads of items each 
time, I use appender to fill it up fast and efficiently. What 
goes in there should not be controlled by the struct itself. It's 
half container, half buffer / appender.
