When first seeing code like this I thought "hey, that's really clean - nice". Then I ran into all sorts of trouble with in a couple of projects that I'd used that invoked the pattern, and went off it rather quickly. I recall Pragdave is of a similar view; he doesn't feel that redefining self inside a block is considered great practice. I'm not sure exactly where I came across his thoughts on it, but it was probably in one of these videos: http://pragprog.com/screencasts/v-dtrubyom/the-ruby-object-model-and-metaprogramming -- You received this message because you are subscribed to the Google Groups "NWRUG" group.
