hpairs?

[Dirk Laurie <dpl@...>]

How does one iterate over all the keys of a table _except_
the ones that ipairs would reach?

Unsuccessful attempts so far:

for k,v in pairs(t) do if not tonumber(k) then ...

for k,v in pairs(t) do if type(k)!='number' then ...

for k,v in pairs(t) do if type(k)!=number or k>#t then ...

for k,v in hpairs(t) do ...
