Your code forces all indices to be numbers. That is not necessary.
It should force all integer keys to lie in a block 1 to #a with
no holes, yes, but string keys are OK. They don't confuse the table
library functions and are quite useful.
E.g. this line from a data file of finite integer sequences:
entry{3,5,17,257,65537, note="all known Fermat primes", OEIS="A000215",
formula=function (n) return 2^(2^(n-1))+1 end}
