Subject: About array to hash conversion

Hi,

I want to convert an array (with pairs [key,value]) to a hash. After
googling a bit I got:

1) Hash[*array.flatten]

But this is not safe as Array#flatten is recursive.

2) array.inject({}) { |m, e| m[e[0]] = e[1]; m }

Too ugly to consider.

3) Hash[*array.flatten(1)]

That's my own attempt. It only works for Ruby > 1.9.

But I am still wondering why...

- Array objects have no "to_h" method?
- Hasy[*array] don't accept the [key,value] pairs (as Hash#to_a calls
return)?

thanks,
holden
