"My crime is that of curiosity"
While I was going through the source code of camping this piece of code that gives you Object like Hash got my attention. Instead of using Hash['key'] it allows you to use Hash.key hence the name "Object Like Hash".
class H < Hash def method_missing(m,*a) m.to_s=~/=$/?self[$`]=a:a==?self[m.to_s]:super end undef id, type if ?? == 63 end
