\section return return - stop the current inner function

\subsection return-synopsis Synopsis
<tt>function NAME; [COMMANDS...;] return [STATUS]; [COMMANDS...;] end</tt>

\subsection return-description Description

\c return halts a currently running function. The exit status is set
to \c STATUS if it is given.

It is usually added inside of a conditional block such as an <a
href="#if">if</a> statement or a <a href="#switch">switch</a>
statement to conditionally stop the executing function and return to
the caller, but it can also be used to specify the exit status of a
function.

\subsection return-example Example
The following code is an implementation of the false command as a fish function

<pre>
function false
	return 1
end
</pre>
