How to require a block in Ruby?

Question

Is there any built in way to require that a block be passed to a Ruby method? I realize I can just raise an exception if block_given? is false, but is there so

Answer 1

If your method required a block, Ruby will prompt it. The raise keyword doesn't require a block, it only prompts a message for handling an Exception.

It could be a method like the above example

def needs_block
 yield
end

needs_block

Or you could require a Proc

def needs_block(&Proc)
    proc.call
end

Anyway, adding raise block_given? would be nice.

Here says:

"The raise method is from the Kernel module. By default, raise creates an exception of the RuntimeError class. To raise an exception of a specific class, you can pass in the class name as an argument to raise".
