local function foo(bar) ... end

is syntactic sugar for

local foo; foo = function (bar) ... end

The difference is only noticeable if foo is recursive. If you use:

local foo = function (bar) ... end

then all references to "foo" within the function will not refer to the
local variable foo because it is not in scope yet.

I personally prefer doing "local function foo (bar) ... end" in my
declarations because I find it aesthetically pleasing and always works
as expected when writing recursive functions.
