What do you mean asking "what happens"?

*Perhaps*, your task may be solved by a tad redesign of
control structures:

def f(i); yield i; end

def g
   5.times { |i|
     break if f(i){|i| i == 3}
     print i, '-'
   }
   puts "\nEnd of g"
end

puts g

They "leave" _current_ block.
In the example you gave above "break" leaves
the block "{ break }".

afaik, "yield" neither here not there.
It does not influence on the behaviour
of "break".
