[Pharo-dev] atRandom & integer agnosticism

Hello community. Kindly consider: | n i r | n := ( 2 ** 256 ) - 1 . "the largest 256-bit value" i := ( 0 to: n ) . "the interval 0 to 2**256-1" "Produce three sets of computed test results." 3 timesRepeat: [ Transcript show: ( r := i atRandom ) ; cr . Transcript show: ( r asByteArray hex ) ; cr . ] According to comments in Pharo library code, atRandom fails for integer magnitudes greater than 2**30 . A reason for this limitation is not given, and it's not clear to a novice such as myself why the computed result of atRandom is permitted to sometimes be in conflict with the semantics of atRandom . Can anyone provide a basic explanation of the rationale for a 'broken' atRandom ? Alternatively, is this a known bug? Thanks. dr
