ruby block and returning something from block

Question

def lab(block)

  puts block.call
  puts \'after\'
end
lab p

Answer 1

return inside a block will return from the method the block is in, not from the block. To return from the block use next (it's named that way because with iterator-methods like each and map returning from the block basically means jumping to the next iteration of the loop).

Note that when the return value is the last evaluated expression in the block, you don't need any kind of return statement at all, i.e. lab { 10 } will do the same thing.
