Sorry Glavo, I cannot support this plan as it appears to be trying to 
rush #1 and #4 into the current release. As I said in the other mail, 
it's very disruptive and requires broader consideration and thinking 
about other locale sensitive APIs.

#3 is the only part of this list that make sense right now.
