luakeys-debug - why are integer indexes wrapped in quotes?

[kalekje]

Just want to ask why integer indexes are wrapped in quotes when using the debug feature. In my opinion, this is misleading as it makes the user believe they are string indexes.

 \luakeysdebug{{1,2,3},{4,5,6}}
-- writes this;

 ['1'] = {
    ['1'] = 1,
    ['2'] = 2,
    ['3'] = 3,
  },
  ['2'] = {
    ['1'] = 4,
    ['2'] = 5,
    ['3'] = 6,
  },
}

Further...

    \begin{luacode*}
        texio.write_nl(luakeys.parse('{1,2,3},{4,5,6}')[2][2]) -- shows 5 as expected
        --texio.write_nl(luakeys.parse('{1,2,3},{4,5,6}')['2']['2']) -- incorrect
    \end{luacode*}

Thank you for reporting this.
