What is the scope of this negative effect of eval() -- current block, current function, or the entire program? It means I should not use my `makeref' function in performace-critical code sections. Fortunately, most of our code is going to have other performace bottlenecks, such as DB IO and interaction over network. -- () ascii ribbon campaign -- against html e-mail /\ http://preview.tinyurl.com/qcy6mjc [archived]
