#47: Cannot pass a :symbol directly as a named parameter
----------------------------+-----------------------------------------------
 Reporter:  cremes at mac.com  |       Owner:  lsansonetti at apple.com       
     Type:  defect          |      Status:  new                         
 Priority:  minor           |   Milestone:  MacRuby 0.2                 
Component:  MacRuby         |    Keywords:  symbol named keyed parameter
----------------------------+-----------------------------------------------
 Here's an example to illustrate. Code was tested against the "testing"
 branch from 20080405.

 class A
   def initialize
     @h = {}
   end

   def setValue(val, forKey:key)
     @h[key] = val
   end
 end

 a = A.new


 a.setValue("triple", forKey::three) # fails

 a.setValue("triple", forKey: :three) # succeeds

 three = :three

 a.setValue("triple", forKey:three) # succeeds

 a.setValue("triple", forKey:'three'.to_sym) # succeeds


 When using the #:: syntax the parser mistakenly views it as an attempt to
 access the method #forKey on Object. At minimum it should probably throw a
 more useful error message and perhaps suggest adding a space between
 colons.
