PEP 42 and Py2.1

[Raymond Hettinger]

I've checked out the Py2.1 beta and my most desired small feature didn't
make it.  To quote PEP 42:
    Generalize eval() to accept any mapping objects for locals and globals.

Is it too late to get this one in?
Is it difficult to implement?
Is there anyway I can help get it done?

Thanks,

Raymond
