In my opinion, foo{|a|...}{|b|...} had better be semantically equivalent to foo(){|a|...}(){|b|...}
at this time. What do you think? For example, we can write the following code.

myif = {|&cond|
   if( cond() )
     {|&then_block| {|&else_block| then_block()}}
   else
     {|&then_block| {|&else_block| else_block()}}
   end
}

I hope we are able to invoke the above Proc object as follows.

   myif{ true }{"then"}{"else"}
   myif(){ true }(){"then"}(){"else"}

The second form is not accepted from incorrect syntax so far, despite the
following accepted code.

   f = myif(){ false }
   g = f(){"then"}
   h = g(){"else"}
