Yes, but all the standard looping constructs, etc. in Ruby are expressed like this too. So it's perfectly consistent with the rest of the language. It's not something new that the user needs to learn just to use this function. This is even more evident in Smalltalk, where *all* control structures, without exception, are expressed in terms of code blocks, possibly with parameters. And Smalltalk has no macros, either, btw. -- Greg -- http://mail.python.org/mailman/listinfo/python-list
