I'd rather use a Hash and lambdas for that since it is more explicit and 
more efficient:

# Note, this is just unsafe dummy URL creation functionality

CREATORS = {
   "foo" => lambda {|val| "http:/foo/#{val}"},
   "bar" => lambda {|val| "http:/google.com/q=#{val}"},
}

def get(name, value)
   CREATORS.fetch name do |key|
     raise ArgumentError, "Cannot find %p" % key
   end.call value
end

Kind regards
