FUNCTION

NAME
        map_mapping - Map a mapping through a function.


SYNTAX
	mapping map_mapping(mapping m, string fun, object ob, mixed extra);

DESCRIPTION
	This function calls ob->fun once for each value in the mapping m
	and returns a mapping constructed with the same indices as m, but
	the values returned from m->fun. The optional extra argument is sent
	to the function as a second argument for each call if present.


EXAMPLE
	The code:

	int foo(int x,int y) { return x*y; }
	map_mapping((["foo":1,"bar":5,"gazonk":6]),"foo",this_object(),2);

	Would result in: (["foo":2,"bar":10,"gazonk":12])
