SYNOPSIS
        string save_value (mixed value [, int format])

DESCRIPTION
        Encode the <value> into a string suitable for restoration with
        restore_value() and return it.

        The optional <format> argument determines the format of the savefile
        to be written:

           -1: use the driver's native format (default).
            0: original format, used by Amylaar LPMud and LDMud <= 3.2.8 .
            1: LDMud >= 3.2.9: no-lambda closures, symbols, quoted arrays
                 can be saved.

        The created string consists of two lines, each terminated with
        a newline character: the first line describes the format used to
        save the value in the '#x:y' notation; the second line is the
        representation of the value itself.

        The format of the encoded value and of the format line matches
        the format used by save_object() and restore_object().

HISTORY
        Introduced in LDMud 3.2.8.
        LDMud 3.2.9 added the saving of non-lambda closures, symbols,
          and quoted arrays, using the new savefile format version 1.
        LDMud 3.2.10 added the <format> argument.
