Subject: TRW: block call question

Page 282 of TRW has the following example:

    <quote>
    def take_block(a, &block)
	puts block.type
	a.times {|i| block[i, i*i]}
    end

    take_block(3) {|n,s| puts "#{n} squared = #{s}"}

    This example also shows the use of braces ({}) as an alias for the call
    method.
    </quote>

Now am I correct in assuming that what was really meant here was ``brackets
([])'' instead, the equivalent using call being

    a.times {|i| block.call(i, i*i)}

?
