Hi, I have to admint `indexes' is not good name, since its behavior (returning values corresponded to keys/indexes) not consistent with one of `index' (returning key/index of value). Let's face it. I decided to declare them obsolete and give proper new names in the future (1.7 and forth coming 1.8/2.0). Do you have any idea of good name for them? I'm not going to remove them, just give warning if you use them. matz.
