Comment(by dev@…):

 I think this would read well:

 {{{
 open_panel.beginSheetModalForWindow @main_window, completionHandler: do
 |arg|
   puts "Hello, open file and user arg is #{arg}"
 end
 }}}

 It's currently invalid syntax. I haven't thought much about the possible
 conflicts or technical viability.

 Along with it, it would be great if we could define methods taking blocks
 and they could be called on the ObjC side with C blocks:

 {{{
 def beginSheetModalForWindow(aWindow, completionHandler: &block)
   # …
 end
 }}}
