Overview
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
raises the exception:
LocalJumpError: no block given (yield)
A more subtle example:
def get_me_a_return
Proc.new { return 42 }
end
get_me_a_return.call
raises the exception:
LocalJumpError: unexpected return
