Hash = Associative Array?

I just noticed the following table on page 167 of the new manual... Table 5-9. Block Types Block Type Description Block! Blocks of values Paren! Blocks of values enclosed in parentheses Path! Paths of values List! Linked lists ***Hash! Associative arrays*** (emphasis mine :) I've been a baby wanting associative arrays in Rebol for awhile. Does this mean we're getting them? If not, what does this mean? Thanks! Keith
