Yeah? I think you have the wrong idea about Boost - have you used
Boost a lot, and in that case, what libraries?

The bulk are generic language-lifting tools, basically giving the
programmer a greater vocabulary. And, even if I bashed math libraries
a bit, I would classify the current (as of 1.39.0) libraries as (and I
did go through each library, and might have counted wrong with a few
units here and there):

1. Language Extensions - 60 (including Statechart and BGL, which are
applicable much more often than the developer realizes)

2. Common Types & Features (often part of newer languages standard
libraries) - 8 (Accumulate, Numeric Conversion, Date, Format,
Random, Regex, Serialization, Xpressive)

3. OS Abstraction Layer - 8 (Filesystem, Asio, Interprocess,
Iostreams, Pool, System, Thread, Timer)

4. Math - 8 (Interval, various Math libraries, Rational)

5. Other Specialized - 7 (CRC, GIL, MPI, Proto, Python, Spirit,
uBLAS, Units)

The first two categories can be characterized as bringing the language
of C++ up to (and beyond) that of newer creations, where the third
category is often part of such a standard library. The number of
libraries belonging to those three categories is 76.

The latter two categories are clearly domain-specific, though. The
number of such libraries is 15.

If you disagree with these figures, I welcome a revised table,
otherwise we can clearly state that domain- and target-*agnostic*
libraries constitute the bulk of Boost, by far.

First of all, I do not understand why we would have to use profanity
in stating that, but alright, I would definitely welcome such a
decision, and it is quite easy; just see the table above. I would
welcome exclusion of those 15 domain-specific libraries...
