You can leave out the last semicolon in a block, but I never do. It doesn't
hurt to have it there, and may save you if later you were to add another
statement after it but forget to add the semicolon to what *was* the last
statement.
I also always put in the return keyword. It enhances readability as you
say, and you don't have to remember that Perl returns the last result.
There are a lot of shortcuts that Perl allows for that I avoid, to enhance
readability and preserve my sanity. Heck, I even put "use English;" at the
top of my programs and use $PREMATCH, $MATCH, and $POSTMATCH instead of $`,
$&, and $' because otherwise, I always have to look them up to remember what
the shortcut variables are. Although, I still use $_, $1, $2, etc. Go
figure...
