You can still use load_buffer for this and keep the function it leaves on the
stack (use a reference for instance).

In Lua 4.0, you can wrap your Lua code inside "return function() XXX end",
run lua_dobuffer and then get the value it returns.

In both cases, you'll have a Lua precompiled Lua function that you can run
at anytime with lua_call(L,0,0).
