+SYNOPSIS
+ object to_object(string arg)
+ object to_object(closure arg)
+ object to_object(object arg)
+
+DESCRIPTION
+ The argument is converted into an object, if possible.
+ For strings, the object with a matching object_name() is
+ returned, or 0 if there is none, as find_object() does.
+ For (bound!) closures, the object holding the closure is
+ returned.
+ Objects and the number 0 return themselves.
+

+ find_object(E), to_array(E), to_int(E), to_string(E)
