next - it s like return  but for blocks   So you can use this in any proc lambda too    That means you can also say next n to  return  n from the block   For instance   puts  1  2  3  map do  e    next 42 if e    2   e end inject  amp       This will yield 46   Note that return always returns from the closest def  and never a block  if there s no surrounding def  returning is an error   Using return from within a block intentionally can be confusing   For instance   def my fun    1  2  3  map do  e      return  Hello   if e    2     e   end end   my fun will result in  Hello    not  1   Hello    2   because the return keyword pertains to the outer def  not the inner block
