There seems to be a typo here, I assume you mean the std::for_each template
:)

And of course requiring the use of a function object declared immediately
before the for_each, not a function declared some distance away.

Ahh, I may have been misunderstanding you again.

Strictly strings are not containers, so I havn't considered them whenever
you said container, I was thinking vector, list, etc.

I find iterators are rarely used on strings because it has operator[] and
most of the operations return an index, not an iterator.

Agree I can't immediately think of places where inheritance is likely to be
useful at high level, but thats no reason to ban it.

Mind you, the concepts of document and filetype could be combined by
deriving a filetype specific document type from the base Document class,
allowing filetype specific overriding of functions like indenting :)

class Perl_document::Document { etc };

Which brings me to the point that some *design* and planning might be
useful before we start hacking.
