Aha, split.  I've now tried split on arbitrary lines in irb, and it works on
them.  But trying split in my little program here yields the following
error:

testget.rb:13: private method `split' called for #<Net::HTTPOK 200 OK
readbody=true> (NoMethodError)

Googling this hairy error gives me no leads.
