\item Makros machen einem das Leben leicht.
\item Formeln -- und auch der ganze Rest -- sehen toll aus.

\item Eigentlich ist das alles gar nicht so schwierig.

\section*{Epilog -- Ein paar Programmiertipps von Rob Pike}
Most programs are too complicated - that is, more complex than they need to be
to solve their problems efficiently. Why? Mostly it's because of bad design,
but I will skip that issue here because it's a big one. But programs are often
complicated at the microscopic level, and that is something I can address here.
\begin{enumerate}
\item You can't tell where a program is going to spend its
time. Bottlenecks occur in surprising places, so don't try to second
guess and put in a speed hack until you've proven that's where the
bottleneck is.
\item Measure. Don't tune for speed until you've measured, and even then don't
unless one part of the code overwhelms the rest.
\item Fancy algorithms are slow when $n$ is small, and $n$ is usually small.
Fancy algorithms have big constants. Until you know that $n$ is frequently
going to be big, don't get fancy. (Even if $n$ does get big, use Rule 2
first.) For example, binary trees are always faster than splay trees for
workaday problems.
\item Fancy algorithms are buggier than simple ones, and they're much harder to
implement. Use simple algorithms as well as simple data structures.
\end{enumerate}
