[Python-Dev] Alternative implementation of interning
Guido van Rossum

I'd like to make all interned strings mortal; this allows some
simplifications to the patch. This would mean that in the following
x = intern('12345'*4)
nx = id(x)
...do something else...
y = intern('12345'*4)
ny = id(y)
nx doesn't necessarily equal ny any more. This is a backward
incompatibility but I'm willing to break programs that rely on this;
it sounds highly unlikely that the author of any such code as exists
would mind it being broken.
(Reminder: this is python-dev, not types-sig. :-)
