Subject: How absurd is this?

Imagine you have in a method a block.  Sometimes you will want that block 
to be executed via a mutex.synchronize() call.  And sometimes you don't 
want to synchronize.

def y
   yield
end

def method_with_a_block
   (dont_lock_here ? method(:y) : @mutex.method(:synchronize)).call do
     puts "This block may or may not be synchronized, depending on whether 
dont_lock_here() returned true or false."
   end
end


Is that a stupid way to get that effect?

The only other alternative that occurs to me is to make the block a 
separate method.

def i_was_a_block
   puts "This code may or may not be syncronized, depending on whether 
dont_lock_here() in method_with_a_block returned true or false."
end

def method_with_a_block
   if dont_lock_here
     i_was_a_block
   else
     @mutex.synchronize {i_was_a_block}
   end
end


What do you all think?
