bsearch should return enumerator when called without a block

This would allow, for example

  values.bsearch.with_index{|val, index| val >= some_array[index]} # => a value

Otherwise, one must use zip/each_with_index and will get an array returned, not just the value seeked:

  r = values.zip(some_array).bsearch{|val, other_val| val >= other_val}
  a_value = r.first
