SYNOPSIS
	mapping map_indices(mapping m, string func, object ob, ...)
	mapping map_indices(mapping m, closure cl, ...)

DESCRIPTION
	ob->func() is called resp. cl applied to every element in the
        mapping, with the key of the element as first argument, and
        then the extra args that were given to map_mapping.
        The data item in the mapping is replaced by the return value
        of the function. ob can also be a file_name of an object.
        If the second arg is a string and the third is not an
	object, this_object() will be used as default.
	Note that if mapping m has more than one value per key, these
	are ignored: the resulting mapping always has one value per key.
	Also note that the behaviour of this function is different from
        map_array().

EXAMPLE
	m = mkmapping(users());
	m = map_indices(m, #'environment);

HISTORY
        In LDMud 3.2.6 renamed from map_mapping() and complemented by map().
