I am saddened when I fire up, say, re.pl, I input something like: $a = $b + $c ...

You really shouldn't be using $a and $b like this. :) As noted in perlvar, these two variables are treated specially by Perl. Though fine in sort blocks (for which they were designed), you should avoid them in regular code so as to avoid unnecessary grey hairs, and wasting time, for example wondering why on earth did Perl complain about $c in your sample code, but not $a or $b?

But I do not think that it is a matter of attitude. I would define it as a matter of temperament, or of view of the world. I am perfectly willing to pay the price of nostrictness nowarningness.

While Larry might applaud your individualism (he invented TMTOWTDI after all), I don't like your chances of finding teammates willing to embrace your view of the world. At least, your nostrictness nowarningness world view would last about 5 nanoseconds on any team I've ever worked in. :)
