1)
str = "apple-orange-grape"

results = []
results << str

pos = 0
while pos = str.index("-", pos)
  pos += 1
  results << str[pos..-1]
end

p results

--output:--
["apple-orange-grape", "orange-grape", "grape"]


2)
str = "apple-orange-grape"

results = [str]
str.scan(/-/) do |match|
  results << $'
end

p results

--output:--
["apple-orange-grape", "orange-grape", "grape"]

Uhg.  Are there alternate names for the perl $ variables?  I thought 
there were, but I can't find them anywhere.
