Because sometimes you need to use real negative indexes.

By the way I can't find reason why not implement that semantic trick with negative index for sequence functions.

I think it will be harmless and useful (at least for me, as I don't like to remember which element table.remove() removes by default and prefer to write

table.remove(some_table_name.subtable, -1)

instead of

table.remove(some_table_name.subtable, #some_table_name.subtable)

)
