I believe this reasoning makes sense in Perl 5 (even if it is not exactly the same as the Perl 6 explanation): It is ‘state’ (with its arguments) that is treated specially on the LHS of =. So (state @a)=... is not special-cased, because what is on the LHS is more than just state. But state(@a) is special-cased, because the (@a) bit is part of the state() call. (Think of state as a function.) So that means state(our @foo) = ... should assign to the package variable @foo once. Right? -- Father ChrysostomosThread Next
