Now you know how a regular function looks like, e.g:
|
|
\begin{haskellcode}
|
|
f :: Int -> Int
|
|
f x = x + 1
|
|
\end{haskellcode}
|
|
But now imagine we need a helper function which is very specific to the current function. In C we would have to define this new helper function at top-level and would probably make it \code{static}.

|
\pause
|
|
\vspace{\baselineskip}

Haskell allows us to \textbf{inline} functions in a few more ways, e.g.:
|
|
\begin{itemizep}
|
|
\item with \code{where}
|
|
\item with \code{let...in}
|
|
\item anonymously (lambda abstraction)
|
|
\end{itemizep}
|
|
\slidep
|
|
A lot of Haskellers really dislike if you put non-generic functions at the top level. So you can still have atomic pieces, but inline the parts which are very specific to the current function. |
