Don't forget though that writing and extending STL algorithms is very much
a part of life. STL was designed to be extended. It is very easy to write
my own algorithm. Following a few *simple* concepts, my algorithm
will work seamlessly with STL as a whole. The ease of implementing
STL algorithms is very much a part of STL's design and interface. The
point here is that *ease of extensibility* is a crucial design factor in
any library. That, we should not forget.
