1. Not requiring parentheses (the original claim) is very different in my eyes from emulating all perl built-in functions; there is much more in this than just parentheses. 2. I hope you didn't intend to say that "primarily" and "only one reason" are the same things. I will allow myself to disagree with such logic. 3. When someone suggests categorical things such like "goto is harmful", "use warnings; is the only way", "function prototypes are better to avoid", then I would suggest not to lose your critical thinking and still learn these tools deeply (that are like all tools are definitely useful in some situations and less useful in others) to form your own opinions. Because it's possible one day you may discover cases when "use warnings;" may stay in your way (say, in short one-liners) or find that "goto" may actually make your code much more readable in some real-life situations. Or maybe (god forbid) you will learn the wonderful world of perl function prototypes and will find their usefulness. :-) Regards, Mikhael. -- perl -e 'print+chr(64+hex)for+split//,d9b815c07f9b8d1e' _______________________________________________ Perl mailing list [email protected] http://perl.org.il/mailman/listinfo/perl
