Short form for adding [] contents?

Hi
Just for getting nice Ruby code:
a=[['a','b'],['d','e'],['g','h','i']]
Is there a method for concatenating the contents of each field?
=> result=['ab', 'de', 'ghi']
How could this bw done nicely?

collect(... a[0]+a[1]...) is not very nice...

2nd:
arr.concat should be renamed to .concat! !
- whats your opinion?

Thank you
Berg

a=[['a','b'],['d','e'],['g','h','i']]
a.map!(&:join)
