Not sure if this really what you want, but you can always redefine any 
functions:

local _print = print
local _write = io.write

function print( ... )
        _print( "@", ... )
end

function io.write( ... )
        _write( "@", ... )
end

print( "hello" )

> @       hello

io.write( "hello" )

>@hello

etc...

Packages (e.g. io) are tables. The global environment (_G) is a table. 
You can redefine any table entry if you are so inclined :)
