And solutions with #inject:

irb(main):010:0> require 'enumerator'
=> true
irb(main):011:0> str = 'a quick "brown fox" jumped "over the lazy" dog'
=> "a quick \"brown fox\" jumped \"over the lazy\" dog"
irb(main):012:0> str.to_enum(:scan, /"([^"]*)"|(\S+)/).inject([]) {|a,m| 
a << m.compact!.shift}
=> ["a", "quick", "brown fox", "jumped", "over the lazy", "dog"]
irb(main):013:0> str.to_enum(:scan, /"([^"]*)"|(\S+)/).inject([]) 
{|a,(m,n)| a << (m||n)}
=> ["a", "quick", "brown fox", "jumped", "over the lazy", "dog"]

But honestly, I found Jan's solution much more elegant.  Great stuff!

Kind regards
