why Tk* classes are freezed?

[Ferenc Engard]

Hi,

I just wonder why the Tk* classes are freezed? If I can change, say,
Object or Class, why I can't change Tk or TkButton?

What do you call "freezed?" ?

svg% ruby -rtk -e 'p Tk.frozen?,TkButton.frozen?'
false
false
svg%

This is my tk.rb:

#
# tk.rb - Tk interface module using tcltklib
# $Date: 2003/09/07 07:10:43 $
# by Yukihiro Matsumoto <[email protected]>
[...]
from line 5621:

# freeze core modules
TclTkLib.freeze
TclTkIp.freeze
TkUtil.freeze
TkKernel.freeze
TkComm.freeze
TkComm::Event.freeze
TkCore.freeze
Tk.freeze

TkButton is indeed not frozen, sorry.

I noticed this because of using the sample Tix.rb from the tcltk-ext
package.

This is a debian unstable.

Sorry. Those are debris. Already those were removed.
