I noticed that this just appeared on RAA:
 
http://www.ruby-lang.org/en/raa-list.rhtml?name=Synchronized+Multi+Iterator

There's also
  http://www.ruby-lang.org/en/raa-list.rhtml?name=Enumerable+tools

See the 'diagonal' method, which, if you follow the link, is documented
in 
  http://redshift.sourceforge.net/enum/op.html
It lets you work with arbitrary enumerables:

for i, j, k in diagonal 1..4, 'a'..'d', ?a..?d
  printf "%4d. %s is 0x%x\n", i, j, k
end
puts

# prints:
#   1. a is 0x61
#   2. b is 0x62
#   3. c is 0x63
#   4. d is 0x64
