Subject: Re: Operator overloading of the subscript operator

Hi,

You won't find this in the Ruby API, because it's a core feature of the 
language and not some special property of a method.

The Ruby interpreter evaluates every expression of the pattern

IDENTIFIER[VAL_1, VAL_2, ..., VAL_n] = VAL

to a call of the []= method:

IDENTIFIER.[]=(VAL_1, VAL_2, ..., VAL_n, VAL)

This should be explained in every good book about Ruby basics.
