I usually use something like

    local f = assert(load(s, s, "t", {}))(logger, RLC)

for this.

And using this approach, you can even hide the fact that you are creating locals:

local input = [[

function (cpu)

  logger.debug("RLC %s")

  cpu.%s = RLC(cpu, cpu.%s)

  cpu.PC = (cpu.PC + 2) & 0xffff

end
]]

... somewhere in your code, this can be "ugly" with as many "local" variables as you want:

local s = [[local logger, RLC = ...\n]] .. input
local f = assert(load(s, s, "t", {}))(logger, RLC)
