Absolutely not. As has been stated multiple times in this thread, a
fully general approach is extremely complicated, horrifically
unreliable, and hopelessly inefficient. The ONLY way to make this sort
of thing any good whatsoever is to know your own use-case and code to
exactly that. Given the size of files you're working with, for
instance, a simple approach of just reading the whole file would make
far more sense than the complex seeking you're doing. For reading a
multi-gigabyte file, the choices will be different.

No, this does NOT belong in the core language.
