-- ';' optimization
-------------------

-- in-between
local foo = 100;local bar = 50
local foo = 100 ; local bar = 50
local foo = 100;bar = 50
local foo = 100 ; bar = 50

-- end of the line
local foo = 100;

-- after function
fish(10);cow(20)
do
  fish(10);return
end

-- f("string") optimization
---------------------------

-- intended result
fish1"cow"fish2'cow'fish3[[cow]]

-- can be optimized
fish4("cow")fish5('cow')fish6([[cow]])

-- added some whitespace
fish7 ( "cow" )
fish8 ( 'cow' ) fish9 ( [[cow]] )
