i'm writing cl library read ms excel(tm) spreadsheets called "xlmanip" (not ready prime time yet -- reads "xlsx" spreadsheets, works 80% use case of "i want operate on cell contents"... digress.) one thing worries me when reading "xlsx" (zip archives in xml format) current zip handling library, common lisp zip, unpacks compressed contents (vector (unsigned-byte 8)) . large spreadsheet, that'll cause issue end user. one alternative i've thought delayed loading -- let-over-lambda closure demand-loads worksheet when needed. however, that's delaying inevitable. are there zip file cl libraries out there return gray stream zip component's contents opposed (potentially large) (vector (unsigned-byte 8)) ? edit: clarification i'm looking zip component function returns stream , not 1 takes stream . functions take stream write zip component's contents directly file associated stream. i'd rather xlmanip reads st...

consider code below : function createfoo() { var val; function foo() {} object.defineproperty(foo.prototype, 'foo', { get: function () { return val; }, set: function (value) { val = value; document.write('foo value set : ', value); } }); return new foo(); } var foo = createfoo(); object.observe(foo, function (changes) { document.write(changes); }); foo.foo = 'bar'; why object.observe 's handler never fired? can object prototype "observed"? (please, answers must not suggest use kind of third party library.) update please, read comments more information , resolution problem. this foo.foo = 'bar'; does not modify neither foo object nor prototype observe not report anything. here version triggers observer on this.val = value; : function createfoo() { function foo() {} object.defineproperty(foo.prototype, 'foo...
