Please answer my question, will it be tested against real world 
benchmarks or microbenchmarks?  The above paragraph, and several 
following paragraphs, are completely irrelevant.

I've no idea what this is meant to mean.

Your final comment sums up perfectly your knowledge of computing in 
2016.  I find it fitting that something so funny is put forward on the 
Python mailing list/news group/whatever, given the derivation of the 
name Python.
