That is very interesting - so then m[i][j] versus m[i,j] becomes a
'prettiness' thing ;)

Personally I prefer m[i][j] because it is consistent and clear.

m[i,j] would make sense if __index took an arbitrary number of 'keys'
but there are probably very good performance reasons why this will not
happen.
