I was disappointed with the book and wish I had bought something else

/me too

I bought it, but I can't read more than a couple of pages without getting annoyed.

you can't have the words "readable" and "uncluttered" alongside the phrase "nested ternaries".

What wrong with

my $baz = $foo == 1 ? 'red'
        : $foo == 2 ? 'blue'
        : $foo == 3 ? 'green'
        :             'yellow';

I don't use it often, but I find it uncluttered and very readable.
