Re: modules and locals

[Rob Hoelz <rob@...>]

local function bar()
end

is just sugar for

local bar = function()
end

Function definitions are just like regular Lua statements; they get
executed in order.  Consider this code:

print(bar)
local function bar()
end

Or better yet, this code:

print(a)
local a = 5

What happens in each case?
