This is broad based conclusion ... I agree that at a lower level
things very much tend to be imperative (machine code) but the picture
is very unclear in higher order abstraction.

I offer perl as a classic example of  ambiguity in that one program in
an imperative style as you could a declarative or OO style ... and its
been said that perl shares several of the attributes of lisp once you
start digging around making it a 'sleeper' functional language.

I guess the point in categorization is the ability to bring a set of
recognized techniques to bear... for example I think that imperative
programs excels wherever one has a problem that is easily
characterized by a state machine.

This however does not guarantee that a developer will then create a
standard state machine in favorite language .. we all tend to reinvent
yet another slightly different version of a state machine instead of

I might be wrong, but once again is not machine code imperative and on
top of that there can exist several functional programming languages ?

IMO the most compelling consideration in choosing a programming
approach revolves around the requirements of the data structure

If XML is being used, then using programming languages that support
XML or things like XSLT/XQuery.

You may find that this is not the right choice for manipulating images
(and blobs in RDBMS are just as bad) or for doing low level binary
operations on a hard drive.
