As far as I can tell
function Var() ... end
will register a global function with the name "Var", even if
you make this declaration inside another function.
But
Var = function() ... end
Will only assign an "anonymous" function to the variable "Var",
and you could have declared "Var" as a local variable.
So they are not really syntactic sugars. There are rules you
have to follow when declaring
function Var() ... end
