Subject: specify a mandatory block parameter

I think I know the answer to this already, but...

Is there a what to make a block parameter mandatory?

<code>
def no_block( p_str )
	puts "#{p_str}"
end

def block( &p_block )
	puts "#{p_block}"
end

no_block #this will cause an exception
block #this doesn't, but is still missing parameter?
</code>

I know, I could just raise my own exception if p_block == nil, just 
wondering why the difference?  Or am I wrong?

Thanks,
