h = Hash[a.zip b] # => {:baz=>1, :bof=>2, :bar=>"world", :foo=>"hello"}
...damn, I love Ruby.
Just wanted to point out that there's a slightly cleaner way of doing this:
h = a.zip(b).to_h # => {:foo=>"hello", :bar=>"world", :baz=>1, :bof=>2}
Have to agree on the "I love Ruby" part though!
How about this one?
[a, b].transpose.to_h
If you use Ruby 1.9:
Hash[ [a, b].transpose ]
I feel a.zip(b) looks like a is master and b is slave, but in this style they are flat.
a.zip(b)
a
b
