Yes it is! It trips people up in practice. Multiplication is supposed to be commutative, yet interchanging its operands can yield a different result. > If you had it your way, ... _My_ way? I was merely pointing out the hate in the Perl 5 way of doing this; I wasn't trying to defend any alternative way (apologies if I gave that impression). I explicitly acknowledged the hate you had pointed out in the Perl 6 way. I don't see pointing out hate in one as being a defence of the other: I am quite open to them both being hateful simultaneously! > print sqrt (9) + sqrt (49) > > would print '4' and not '10'. I doubt many people would expect it to > print 4. Yup, that's hateful. Smylers
