I'm been writing a small Ada program for a personal project.  I
usually write C++/STL for such projects due to my background, but
because I wanted to get more practice with Ada, I decided to do the
project with Ada.  All has been well, except that I've been a bit
surprised about generic containers.

I was looking for a simple queue data structure, but I noticed there
is not a standard Queue container.  I managed to make a Vector work
like a Queue, but it feels a bit awkward:  Append() for a "push" and
First_Element()+Delete_First() for a "pop".  I realize that I can
write a wrapper interface and create my own queue, but queues are so
common I can't believe we have Hashed_Maps and not a simple Queue
container.

I'm just curious what the reasoning was behind not providing a Queue
container?  Is there some Ada philosophy behind this?  Or is there
something similar to the C++ Standard Template Library in Ada?
