 where $\Sigma^*$ is in our case the set of all strings (what follows in this section
 also holds for any kind of ``domain'', like the set of all integers or

 is about strings, for example $P(s)$ could be ``the string $s$ has
 an even length'', or ``the string $s$ starts with the letter
 \texttt{a}''. Every such property carves out a subset of strings from
