foo goo { 'bar' }

The first is the same as:
     foo( goo(){ 'bar' } )
     foo( goo do 'bar' end )

The second is the same as:
     foo( goo ){ 'bar' }
     foo( goo ) do 'bar' end


def foo( *args )
     puts "foo args: #{args}"
     puts "foo block result: #{yield}" if block_given?
     "foo return value"
end

def goo( *args )
     puts "goo args: #{args}"
     puts "goo block result: #{yield}" if block_given?
     "goo return value"
end

foo goo { 'bar' }
puts '-' * 40
foo goo do 'bar' end

#=> goo args:
#=> goo block result: bar
#=> foo args: goo return value
#=> ----------------------------------------
#=> goo args:
#=> foo args: goo return value
#=> foo block result: bar
