i doubt it.  i don't know too much about the call frame structure, but the Lua 
core doesn't handle the 'hidden argument' case.  it's purely syntax sugar.  
the core just sees the expanded case, with an explicit self parameter.

as mentioned above, the core language doesn't handle the colon operator. it's 
just syntax sugar.

personally, i like the fact that the self parameter isn't really hidden.  it's 
not rare for me to use an explicit 'self-like' parameter and later use that 
very same function with a colon operator.

knowing that "self" isn't a special case makes it much easier to handle.
