Lua 5.2 can, with a light C function. (Of course, you should never expose
that value to any Lua code that could try to call it.)

I have hidden none lua_CFunctions in Lua before just by casting it to the expected signature, when I needed to call in C I recast it to the correct type and called it; which is perfectly valid C. Casting to a void pointer is however either undefined or implementation defined.
