IronPython, IronRuby, JRuby and the Python and Ruby Communities
My commentary on the Ruby community reaction to IronRuby and comparisons with both JRuby and IronPython: IronPython, IronRuby, JRuby and the Python and Ruby Communities Of particular note is that the loss of 'multiple engines' from IronPython 1 to IronPython 2 (the jump to the DLR) may be more significant for IronRuby than it is for IronPython.
