That's if foo etc. are variables.  In the Perl example they're
strings.  So you'd have to do:

  hash = Hash[*%w{ foo led bar tender }]

or equivalent.

There's been a lot of array-to-hash-to-array discussion here.  A
search for "to_h" at
<http://blade.nagaokaut.ac.jp/ruby/ruby-talk/index.shtml> will turn up
a bunch.
