The lambda syntax (=>) is only for when there is a single return 
statement in the function literal:

As Kenji Hara has shown, you can have more than one expression in the 
return statement by taking advantage of the comma operator but 
personally I would use something else instead: the longer syntax, a 
local function, etc.
