Hello,
even in preview 6 it's not possible to use titles for a tk rootwindow:

root = TkRoot.new {title "foo"}

generates a mainwindow with just "tk" as title. Enviroment: win32.

Any suggestions?

Thanx

Eric.

The minimal example is :

svg% cat b.rb
#!/usr/bin/ruby
class A
   def a
      warn "ok" if block_given?
   end
end

class B < A
   attr_accessor :b

   def a
      self.b = super
   end
end

B.new.a {}
svg%

svg% b.rb
svg%

The problem is in NODE_ATTRASGN ({BEGIN,END}_CALLARGS)

Wow, I was surprised a basic bug like this survives that long.
Thank you for finding it.

Not only in it, but also in NODE_[FV]?CALL.

I made my own fix, but yours seems better. Could you commit the fix?
