Result of ``a is b''

[Terry Reedy]

For what it's worth: the idea of changing the meaning of 'is' been
discussed on the PyDev (development) list for a couple of days.  GvR posted
this a few hours ago ('the code' refers to an example misusing 'is'):

"I'm ready to pronounce.  The code is buggy.  There are good reasons to
keep 'is' the way it always was.  The definition of 'is' ain't gonna
change.  So be it"
