in reply to A guide to coding Perl

One thing I like to avoid is excessive brace nesting. Mostly because I find it hard to make sure I've got the end braces right. Yes smart editors help, as does indentation, but I like the perl "statement unless condition" syntax a lot in my loops.

What do I mean?

well I often see code like

while (cond1) { if (cond2) { statement; if (cond3) { statement; statement; for (range) { something; something; something; } } } else { last; } }
What I prefer to see/write is
while (cond1) { last unless (cond2); statement next unless (cond3); statement statement for (range) { something something something } }


Enter any 47-digit prime number to continue.

    Yes, yes, yes. Fallthrough is concise, natural and seemly.

    To my knowledge, I've only met two people, Pascal lovers both, who could not abide fallthrough. In their code, an if statement that could return was always followed by an else clause that contained the rest of the routine.

    To be fair: a couple more spaces in your indents and your first version would read much better.
