I've heard that complaint before, and I honestly don't understand it. Among the reasons people use OO is so that the meaning of `$obj->meth` can be determined at run time, not compile time. If `each $x` is so confusing in Perl 5.14+ that it shouldn't be used "deep in the call stack", isn't that also true of method invocations? -- Aaron Crane ** http://aaroncrane.co.uk/
