Adam,
PS: Is there a better way to do the following?
Can it be done in a single line?:def describe_set set
s=""
set.each {|o| s+= "There is a #{o} here. " }
s
end
How about:
def describe_set(set)
set.inject("") {|s,o| s += "There is a ${o} here. "}
end

You don't need the assignment. #inject automatically sets 's' to the
previous value of the block:
set.inject("") {|s,o| s + "There is a ${o} here. "}
The assignment doesn't hurt anything, but it obscures what's really
happening. For example, this would give the wrong answer:
set.inject("") {|s,o| s += "There is a #{o} here. "; print "Looping\n"}
regards,
Ed
