Creating a new function by composition: `compose'

This abstraction takes two input functions as input arguments and returns a new function composed ot the two inputs.

This lambda-abstraction is very useful for example in defining the abstractions for addition and multiplication. See also section basic:add and basic:mult.
$\begin{lstlisting}[language=Scm]{} (define compose (lambda (f g) (lambda (x) (f (g x))))) \end{lstlisting}$
