Re: [MacRuby-devel] C-level blocks (issue #712)?

You are right, still a gotcha tho:

Ruby 1.9.2:

  def foo(a, b={})     b[:handler].call if b.has_key?(:handler)   end   foo :bar, handler: Proc.new do     puts 42   end

`new': tried to create Proc object without a block (ArgumentError)

Works if you add parentheses though : def foo(a, b={}) b[:handler].call if b.has_key?(:handler) end foo :bar, handler: (Proc.new do puts 42 end)
