Sorry, you lost me with your example.

My block is being bound with do/end rather than {}. In your examples, 
you're using {} which has tighter binding and the syntax error is 
expected.

foo 'hello' do  puts 'in block'; end

works just find but this isn't the same as what I'm asking. I'm binding 
the lambda function as a hash value.

Or...maybe I'm missing something obvious.
