 /*
+ *  Document-class: LocalJumpError
+ *
+ *  Raised when Ruby can't yield as requested.
+ *
+ *  A typical scenario is attempting to yield when no block is given:
+ *
+ *     def call_block
+ *       yield 42
+ *     end
+ *     call_block
+ *
+ *  <em>raises the exception:</em>
+ *
+ *     LocalJumpError: no block given (yield)
+ *
+ *  A more subtle example:
+ *
+ *     def get_me_a_return
+ *       Proc.new { return 42 }
+ *     end
+ *     get_me_a_return.call
+ *
+ *  <em>raises the exception:</em>
+ *
+ *     LocalJumpError: unexpected return

+ *     end
+ *     me_myself_and_i
