Sorry this is my bug... "a" recursively

as badly with lua-tables
such a good container,
but it does not present in any language :-(

2008/3/12, Alexandr Leykin <>:

How to know to be a key in lua table? Without use pairs/ipairs/next?

a = {a,b,c,d}

a.a => nil, but key "a" present in table!
a.f => nil, but key "f" not in table!

Than differ a.a and a.f??? (a.a - key in the table a, a.f - not)
