How do you expect `myTable[ myTable.len ][ myTable[ myTable.len ].len ]` to
work? If the table has holes, that means `myTable[myTable.len]` will not make
much sense, and indexing seqs by their length errors because Nim is 0 indexed.
You might want a `seq[(int, seq[int])]` here, from my knowledge indexing that
will not be slower than an ordered table, then you can do `myTable[^1][1][^1]`
(or `myTable[^1].seqField[^1]` if doing `seq[tuple[index: int, seqField:
seq[int]]]`). If you are confident `myTable[myTable.len]` makes sense you can
do `myTable[myTable.len][^1]` with what you have.
