"I prefere the and put at the end of the line and all and aligned: the same for or and for thernary like ? and : because somenting at the end of line is easier to spot."

I emphatically disagree! The easiest stuff to see is at the start of the line. I frequently break complicated expressions over lines so that it is easier to understand them. For example, the following test from a C++ project I'm working on right now could be laid out several ways:

if (currMaj < bestMajVer || (currMaj == bestMajVer && currMin <= bestM +inVer)) // Current image is no better than the best so far if (currMaj < bestMajVer || (currMaj == bestMajVer && currMin <= bestMinVer) ) // Current image is no better than the best so far if ( currMaj < bestMajVer || (currMaj == bestMajVer && currMin <= bestMinVer) ) // Current image is no better than the best so far

To my eye the last version is much easier to understand than the previous two.

One of Perl's features that I really like is the provision of statement modifiers because, for short statements at least, I can get compact expressive code with the important bits in the right order:
<do this interesting thing> <while/for/if> <something vaguely interesting>.

For the same reason the default increment operator should be pre-increment (++$thing) instead of the cargo culted post-increment operator ($thing--). There are places where post-increment must be used, but they are rare and the default should always be pre-increment just because the operator is easier to see and the operation is less surprising.

Optimising for fewest key strokes only makes sense transmitting to Pluto or beyond

    Hello GrandFather

    > I emphatically disagree!

    :) as I told, I suppose is a matter of taste. I tend to use something like:

    # complex clause if ( defined $thing and $thing > 3 and $thing <= 42 and 0 == $thing % 2 ) # ternary print (defined $thing and $thing > 0) ? $thing : 'not';
