So it's a good idea to repeat functionality in more than one place?  That
is it's a good idea for castor to include equivalent functionality that
already exists in boost.  This effectively increases the total amount
of code being dealt with rather than decreasing it.  If a library (or any
code) is simpler and smaller because it includes a lot of code all ready 
existent
then shouldn't ALL code (including boost) copy in the functionality from
all the libaries it uses.  Basically, the idea that a library is simpler 
because
it doesn't include other libraries doesn't make sense when carried to it's
logical conclusion.

If you really believe this, then you'll have to conclude that no one will
want to use your library either.

Of course if there is a specific problem with some boost libraries or
boost libraries in particular, that's another issue entirely.  And an 
interesting
one.

In my professional life, I often come accross programmers who shy
away from boost libraries.  They'll spend weeks (of their employer's
time and money) to re-create some small functionality which is already
in some library and could be included with just 2 days of study.

Which is the problem.  Boost libraries aspire to be more generic
and that means a higher level of abstraction.  This means that it
takes a lot more effort to use the library than it first appears.
The idea of a library makes it sound like "just drop it in"  but
then it turns out one has to spend a couple of days figuring it
out and it seems easier just to "roll your own".  Of course it isn't
but that's not apparent even after the fact.

Anyway. I'm very intrigued with this library idea.
