I know that this is a silly argument, but Word is used internally in RULES for fromIntegral to generate good code for conversions between sized integers. Since Word{8,16,32} and sometimes Word64 is represented as data-wrapped Word#, it's easy to implement many conversions by delegation to the conversion with source or target type replaced with Word. This was actually what triggered me to add missing instances for Word (Num and Integral were needed). -- __("< Marcin Kowalczyk * qrczak@knm.org.pl http://qrczak.ids.net.pl/ \__/ ^^ SYGNATURA ZASTÊPCZA QRCZAK
