>That's why most of the enumeration methods in Ruby match the names of similar methods in Smalltalk ("collect", "reject", "select", etc.) and not the corresponding names in functional languages ("map", "reduce", "filter").
Ruby has both, actually; "map" is a synonym for "collect", "reduce" is a synonym for "reject", and "filter" is a synonym for "select" (well, actually, they are both synonyms for "find_all"). And the non-Smalltalk names seem to have had more influence on newer methods, e.g., Enumerable has filter_map, but not select_collect, even as a synonym.
