You just need to get the component programming religion! and
get away from using FILE*. There isn't anything fundamentally
different from using a fake FILE* and using a template with a
different InputRange. If that's still unacceptable, you can
create an InputRange that is a class with virtual functions
empty(), front(), and popFront(), then use derived classes for
the File or string.
One of the things that made me a fan of OO, was when I understood
the types of file manipulations that were possible with the IO
abstractions
available in most languages in comparison with was is possible in
a pure procedural world.
Sure iostreams, Java IO, .NET, Smalltalk might offer complex IO
models, but
they are quite powerful for doing generic code over abstract data
sources.
