Hello,

Here is a summary of ruby-dev last week.

[ruby-dev:24240] on enabling tcltk-stubs

  Hidetoshi Nagai, who is a maintainer of Ruby/Tk, called for help since a
  program abort on exit of Tcl/Tk interpreter as follows:
    $ /usr/local/bin/ruby -r tcltklib -e 'TclTkIp.new._eval("exit")'
    Tcl_Release couldn't find reference for 0x814ed38
  A trial fix of this issue was done, and he asked for someone to check
  if the library works fine.
  Also, he asked for someone to try multi-tk.rb and remote-tk.rb, since
  those have been improved from the previous version.

[ruby-dev:24250] DateTime#to_time

  Tadayoshi Funaba posted a specification and a prototype of following
  methods.
    - DateTime#to_time, #to_date
    - Date#to_time, #to_datetime
    - Time#to_date, #to_datetime

  Significant points are as follows:
    - It is not ensured that yyy.to_xxx.to_yyy is equal to yyy.
    - to_time
      * It always returns local time.
      * It may not return intended result because of summer time and
        leap second.
      * 'usec' is rounded.
    - to_date and to_datetime
      * Time zone information is lost, but time difference is left on
        DateTime.
      * Leap time is not considerable.
