Globalization API - Sample Use Cases

I agree that object literals are more verbose, but they are also more
readable. I did hear some complains about formatting strings missing from
the latest spec (we had them before), and mostly from people that know how
to use them (I still need to look up CLDR docs to write a semi complex one).
The easy solution to that is to add 2 more fields to the options (or have
them as separate parameter):
1. pattern - as is, I know what I want - MM/yy always generates 9/74 no
matter the locale.
2. skeleton - MM/yy will get you closest matching pattern for a given
If pattern or skeleton fields are specified, we ignore the rest of the
We had this approach before and removed it from the spec to simplify the
API, but it shouldn't be hard to get it back in.
