Subject: [ruby-talk:27861] how comes this works?

how comes this works? 

def e();yield "block was given!";end
def f();e();end
f(){|o|p o}

=>"block was given!"

while this, not surprisingly, does not

def e(&pr);pr.call("block called");end
def f();e();end
f(){|o|p o}

=>Ruby2:1:in `e': undefined method `call' for nil(NameError)

intended behaviour?

(sorry for violating the styleguide)
