Type hints can be put in separate stub files and will be put in separate 
files for the stdlib.  If a client want to pay you to write type stubs, 
and you cannot stand to do it for even for pay, I am sure you will be 
able to subcontract the work.  I am sure someone will write python 
probrams to make the process easier.

Many Pythonistas would be glad to see more work, not bitch about it.

Readability?  Unchanged (at least for your own code and much of the rest).

??? Python objects will still be dynamically typed.  For the present, 
compilation will be completely uneffected.

Dynamic typing? unchanged.

Sturla, I *know* you must have heard of numpy?  cython?
