List comprehension: @{text"[e. q\<^isub>1, \<dots>, q\<^isub>n]"} where each
qualifier @{text q\<^isub>i} is either a generator \mbox{@{text"pat \<leftarrow> e"}} or a
guard, i.e.\ boolean expression.

\section{Map}

Maps model partial functions and are often used as finite tables. However,
the domain of a map may be infinite.
