Easter egg (and rant) of the day

[Alexis Nikichine]

Hello,

function isOk()
{
return
( this.status != cBad )
&& ( this.status != cIll )
&& ( this.status != cDead );
}

What does this function returns, and why ? Been hardly bitten today...

It returns undefined as automatic semicolon insertion inserts a
semicolon after the return so the code is exected as

function isOk()
{
return;
( this.status != cBad )
&& ( this.status != cIll )
&& ( this.status != cDead );
}

which yields undefined.
