script so that each part you want to keep unchanged is assigned to its
own variable in long string format, e.g.,
local bas = [[
_onA_ = function(x)end]]
return doSomething(x)
... in Lua 5.2 you can execute the value stored in bas using load.
And you'd still have the variable name and its value to concatenate
into the string for the new file unchanged.
I'm not certain how to do this in Lua 5.1; I recall that load's
behavior was changed somewhat in 5.2.
