I'm not dismissing the need for such a tutorial, but I suspect new users would be better served by a tutorial on how Perl code is chunked with a section on operator precedence. That way, you can include things like
- Creating a list of hashrefs using map{}
- Why doesn't print (3+5)/3; DWIM?
- Why do some people do things like my $x = $hash_of_stuff{+shift}?
The real topic is a larger one than the one you're looking at.
Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
