What you describe gives me a flutter in the stomach. The convenience to some doesn't justify the added complexity. Conditional white-space sensitivity seems to invite derision, not celebration. I also realize that my gut isn't a good predictor for what goes into Perl. We got "//" even though it's not needed. And we got "and", "or", and "not" (and "err"--sigh) specifically as a way o skip parentheses, even though I find code easier to read when it has punctuation to guide my eye, not words that sink into the general texture of function calls. Larry obviously feels otherwise. See Rule 1. --tomThread Previous | Thread Next
