Confusing error message for nil-indexed C arrays

Hi Mike,

today I got this error message (by accident in a buggy program):

> local array = (require 'ffi').new('int[?]',1) ; array[nil] = 1;
stdin:1: 'int [?]' cannot be indexed

Arguably this is confusing. Contrast the error message if we use a
nil-indexed Lua array instead:

> local array = {0} ; array[nil] = 1
stdin:1: table index is nil

Q: Could we have something like "'int[?]' index is nil" instead?
