Are you expecting it to behave equivalently to == for numbers originating from numeric processes (i.e., getting standard stringification)? It doesn't: $ perl -MData::Float=nextup -lwe 'print nextup(42) == 42 ? "yes" : "no"; print nextup(42) eq 42 ? "yes" : "no"' no yes Behaviour also differs between == and eq on NaN. Having ~~ mean eq when the rhs is a plain defined scalar is certainly defensible, but don't expect it to be terribly useful on numbers. Just to be clear, trying to split ~~ into stringy and numeric cases would be worse. There's no sane version of this that gets us decent implicit numeric behaviour. -zeframThread Previous | Thread Next
