Well, if I use a single var, "for v in tbl", I mean ipairs because I
don't need an extra var for the keys, they are easily recoverable if
needed - for normal Lua list tables starting at 1. That doesn't happen
with map tables, I need the extra var to correlate keys and values.

But I see your point, though.

I'm not asking for any change in Lua, I'm quite happy with the way it
is. I just would be happier if I could use "for v in t" naturally, but
the metamethod way is fine with me.
