Ah, but there are thousands of lines of Lua code using ipairs; why break them?

What will happen is a compat52 library, which will re-introduce all
the things we liked in 5.1 ;)

It's not a common use-case.  I tend to define little iterators called
'iter' or 'list' which just iterate over the values (in order ;))

PS I have mixed feelings on this one. On the one hand, if I was
introducing a person to the language, then having both pairs and
ipairs to explain would be tricky - whereas everyone gets numeric for.
  On the other hand, 'active' deprecation leaves little patches of Lua
code out there that tend to break nastily - like 'for k,v in t do'
which I was very fond of at the time.
