Not (easily*) doable with ltokenp because tbl can be an arbitrarily
long expression:

--> meaning (foo[(bar or {}).baz](arg).x or {}).bla

To deal with expressions, you need an AST, which is what Metalua provides.

(* technically it is doable with ltokenp because one would have to
essentially consume an arbitrary number of the tokens and build an
AST, but then you are just reimplementing a subset of Metalua)
